Choose the right window winder in 60 seconds
Six questions, one winder. Australia’s widest COLORBOND®-matched range, direct replacement for Whitco®, Stegbar®, Boral®, Dowell®, Trend®, AWS®, Bradnam’s® and Wideline®.
Replacing a window winder sounds simple until you open Bunnings and see fifteen variants. Left hand or right? Lockable or not? 300 mm or restricted chain? Stainless steel or zinc? And then there’s matching the colour to your window frame. This guide walks you through every decision in the order you should make it, so you end up with the right winder the first time. If you already know what you need, jump straight to our full window winder range.
The 60-second decision
Most window-winder replacements come down to six questions. Work through them in order and you’ll land on exactly one product:
- Which side does it sit on? Left hand or right hand.
- Do you need it to lock? Lockable keyed-alike or non-keyed.
- How far does the window need to open? Standard 300 mm chain, or a restricted 100, 120 or 150 mm chain for pool safety and child safety.
- Is the home near the coast? Standard zinc chain, or stainless steel for marine environments.
- What colour is the existing winder or frame? 16 finishes, including COLORBOND®-matched colours.
- How many do you need? Single, multi-pack or set trade pricing — every lockable winder in a multi-unit order is keyed alike to one key.
In a hurry? Jump straight to the common scenarios table and pick the row that matches your window, or check the full combinations table to see exactly which hand, lock, chain and colour combinations we stock.
1. Left hand or right hand?
This is the question that catches the most people out. The hand of a winder isn’t about which hand you use — it’s about which side of the window the winder body sits on when you’re standing inside the room looking out.
Left hand
Body on the left, viewed from inside
Most common configuration on Australian awning and casement windows. Chain attaches to the sash on the right. Available in all 16 finishes.
Right hand
Body on the right, viewed from inside
Mirror image of the left hand. Common where the window opens against a wall, beside a door, or in mirrored pairs. Lockable, in 10 finishes.
If you’re replacing an existing winder, the simplest test is to look at the broken one before you order. The chain attaches to the sash on the opposite side from the winder body. Still confusing? Take a photo from inside the room with the window open and email it through — we’ll confirm before you buy.
Right hand winders come lockable only, in White, Black, Brown, Silver, Surfmist®, Monument®, Paperbark®, Primrose®, White Birch® and Merino. See the combinations table for which right hand colours also come with a stainless or restricted chain.
2. Lockable or non-keyed?
A lockable winder has a key barrel built into the body. Push a button to lock the mechanism in place; turn the key to unlock. A non-keyed winder is mechanically identical minus the lock cylinder.
Lockable (Keyed Alike)
Built-in key barrel
- Ground floor or accessible windows
- Pool fence compliance (with restricted chain)
- Strata, rental, or insurance requirements
- All winders keyed alike — one key opens every winder you order
Non-Keyed
No key, simple operation
- Upper floor windows with no external access
- Aged-care or accessibility-focused homes
- Lowest-cost replacement option
- Same body, mounting and chain — just no lock
- Left hand only
🔑 One key, every winder. When you buy multiple lockable TradeBase winders — whether it’s a 6-pack renovator or a custom trade order — every winder in the order is keyed alike to the same key. Our 5-pin C4 profile also matches most existing residential locks, so you can usually have your house keys, door cylinders and winders all on a single key.
Popular lockable: White Left Hand Lockable Keyed Alike and White Right Hand Lockable. Popular non-keyed: White Left Hand Non-Keyed.
3. Standard 300 mm chain, or restricted?
This is the most safety-critical decision and it’s where most home renovators get it wrong. The chain length determines how far the window can open.
Pool fence compliance — AS 1926.1. Windows opening into a pool zone must be limited to a 100 mm gap. A standard 300 mm winder will fail council inspection. Same rule applies to windows in homes with young children that are 2 metres or more above ground level (BCA child-safety provisions).
Standard 300 mm
Full ventilation, standard awning
- Window opens about 300 mm at the bottom edge
- Default for almost every awning and casement window
- Full natural ventilation, easy to reach over to clean
- Use anywhere a restricted opening isn’t required by law
Restricted 100 / 120 / 150 mm
Pool safety & child safety
- 100 mm — window opens to a maximum 100 mm gap. Use for pool zones (AS 1926.1)
- 120 mm and 150 mm — limited opening where a slightly wider gap is acceptable
- Upper-floor windows where children are present
- Still allows ventilation while preventing access
Restricted chains come in both left and right hand, lockable, with zinc or stainless chain on selected colours. The widest restricted range is in White, Black, Brown, Surfmist® and Monument®. Examples: White RH 100 mm Restricted, White LH 100 mm Restricted Stainless, Black LH 150 mm Restricted, Monument® RH 120 mm Restricted. Note: a restricted chain doesn’t remove the requirement for a pool fence — it’s an additional compliance layer.
4. Standard zinc chain, or stainless steel?
The chain is the part that wears and corrodes first. The winder body is generally rated for the life of the window, but the chain takes the weather.
Standard zinc chain
Correct for inland and most suburban Australian homes. Backed by our 12-year warranty.
Stainless steel chain
Choose if the home is within ~1 km of the coast, exposed to salt spray, or in any marine corrosion zone. Eliminates rust-streak down the sash. Stainless winders are lockable.
Stainless options across the colour range: White RH Stainless, Surfmist® Stainless, Monument® LH Stainless, Woodland Grey® Stainless, Stone Beige Stainless.
5. Match the colour to your window frame
TradeBase carries the widest COLORBOND®-matched winder range in Australia. Match the winder body to the window frame so the hardware disappears visually.
Whites & creams
White, Surfmist®, Merino, Primrose®, White Birch®
Greys & silvers
Silver, Soft Sheen Silver, Silver Satin Chrome, Woodland Grey®
Earth tones
Dune®, Paperbark®, Stone Beige, Brown, Jasper®
Black & dark
Black, Monument®
Not every colour comes in every configuration — check the combinations table below. Matching to a non-COLORBOND® powder-coat finish? Send us a photo and we’ll suggest the closest match before you buy.
6. How many do you need? Packs and trade pricing
Every lockable winder in a multi-unit order is keyed alike to a single key, so however many winders you fit, you only ever carry one key.
Single
Every combination in the table below. Ships next business day from Australian stock.
6-pack renovator (lockable)
All keyed alike to one key. Left hand. White 300 mm | Black 300 mm | Black restricted 100, 120, 150 mm

Every combination we stock
Find your colour, then read across. ✓ means we stock it. Restricted cells show the chain lengths in mm; they are lockable with a zinc chain unless marked SS (stainless steel, lockable) or NK (non-keyed). A dash means that combination isn’t available — email us and we’ll suggest the closest match.

Brand compatibility — what does TradeBase replace?
TradeBase winders are direct mechanical replacements for the major Australian window-hardware brands. Mounting holes, chain coupling, and key-barrel cut-outs all match — you can usually swap the winder without modifying the frame. Suits timber and aluminium awning and casement windows with butt or hook hinges or non-friction stays.
- Whitco® — including the MK8 chainwinder family: W380116 (lockable white), W380216 (keyed alike white), plus brown, black and silver MK8 variants and the standard non-locking chainwinder. Our 5-pin C4 keyed-alike system matches the original CYL4® key profile.
- Stegbar® — including timber and aluminium awning chainwinder fitments
- Boral®
- Dowell®
- Trend®
- AWS® (Aluminium Windows & Screens)
- Bradnam’s®
- Wideline®
If your existing winder is a different brand, it’s still likely compatible — the Australian industry standardised on the same mounting pattern decades ago. Email us a photo and we’ll confirm fit before you order.
What it gets called — the same part, different names
Half the difficulty in buying window hardware is that the trade, the manufacturers and the hardware aisle all use different words for the same thing. If you learned on one system and are buying against another, this is the translation:
| What we call it | Also known as |
|---|---|
| Window winder | Chainwinder, chain winder, window crank, window opener, window operator, awning winder, casement winder, winder handle |
| Lockable winder | Locking winder, keyed winder, key winder, security winder, keyed alike winder |
| Non-keyed winder | Non-lockable winder, non-locking winder, standard winder |
| Restricted chain | Limited opening winder, 100 mm restrictor, child safety winder, pool safety winder, window restrictor |
| Hand (left / right) | Handing, LH / RH, left-handed, right-handed, drive side |
| Chain | Winder chain, drive chain, link chain, sash chain |
| Mounting bracket | Riser, riser bracket, packer, spacer, adaptor plate, height adaptor |
| Whitco® MK8 | W380116, W380216, MK8 chainwinder, Whitco® window winder, CYL4® keyed |
Two words that do not mean the same thing: a winder drives the sash open and shut on a chain; a stay is the arm that holds the sash at a set position with no drive mechanism. If your window opens by pushing it and latching an arm, you are looking for a stay, not a winder. And a window lock is a separate part again — see the Window Lock Buying Guide.
Brackets, spacers and accessories
If your replacement winder doesn’t sit flush on the existing mounting holes, the issue is usually a difference in body height. We carry purpose-made riser brackets to lift the winder body to the correct height in 16 mm and 20 mm options:
For accessibility, our Easy Grip Handle Adapter is a 45 mm knob that fits over a standard winder handle — useful for residents with arthritis or limited grip strength.

Once you’ve ordered — how to install
Replacing a chain winder takes about ten minutes per window with a single Phillips-head screwdriver. We’ve written a full step-by-step with photos: see How to replace a chain window winder. If your old chain has been sagging or skipping under load, our Anti-Sagging Chain System explains the engineering reason and how the TradeBase keeper plate fixes it.

We stock replacement window winders to suit Whitco®, AWS®, Boral®, Bradnam’s®, Dowell®, Stegbar®, Trend®, Wideline®. Each brand page lists every compatible part and what to measure before ordering. See all replacement hardware by brand.
Window winder FAQ
Stand inside the room and look at the window. If the winder body sits on the left side of the frame, you need a left hand winder; on the right, a right hand winder. The chain always attaches to the sash on the opposite side from the body. It has nothing to do with which hand you use.
Yes. TradeBase winders are direct mechanical replacements for Whitco® chainwinders, including the MK8 family (W380116 lockable and W380216 keyed alike) and the standard non-locking chainwinder. The mounting holes, chain coupling and key-barrel cut-out match, so the winder normally swaps over without modifying the frame. The same applies to Stegbar®, Boral®, Dowell®, Trend®, AWS®, Bradnam’s® and Wideline® winders.
A restricted 100 mm chain. Under AS 1926.1, windows opening into a pool zone must be limited to a 100 mm gap, and a standard 300 mm winder will fail council inspection. The same restriction applies to windows 2 metres or more above ground level in homes with young children. A restricted chain is an additional compliance layer and does not replace the pool fence.
100 mm, 120 mm and 150 mm, in both left and right hand. All three lengths are available in both hands in Black and Brown, and in right hand in White, Surfmist® and Monument®. Stainless restricted chains are available in White, Black, Dune®, Paperbark®, White Birch®, Woodland Grey® and Silver Satin Chrome. See the combinations table on this page for every option.
Yes. Every lockable winder in an order — a 6-pack or a trade order — is keyed alike to a single key. The 5-pin C4 key profile matches the Whitco® CYL4® key and most existing residential locks, so house keys, door cylinders and winders can usually run on one key.
Only if the home is within about 1 km of the coast, exposed to salt spray, or in a marine corrosion zone. A stainless chain stops rust streaks running down the sash. For inland and most suburban homes the standard zinc chain is correct and is covered by the 12-year TradeBase warranty.
16 finishes: White, Black, Brown, Silver, Soft Sheen Silver, Silver Satin Chrome, Merino, Stone Beige, and the COLORBOND®-matched Surfmist®, Monument®, Dune®, Paperbark®, Primrose®, White Birch®, Woodland Grey® and Jasper®. Every colour comes in left hand; right hand is available in White, Black, Brown, Silver, Surfmist®, Monument®, Paperbark®, Primrose®, White Birch® and Merino. Not every colour comes in every chain and lock option, so check the combinations table on this page.
About ten minutes per window with a single Phillips-head screwdriver. Unscrew the old winder, unhook the chain from the sash, fit the new winder to the same holes and reconnect the chain. A full illustrated step-by-step is in the How to replace a chain window winder guide.
The difference is usually body height. Fit a TradeBase riser mounting bracket, available in 16 mm and 20 mm in white, black and grey, to lift the winder body to the correct height without drilling new holes.
A winder drives the sash open and shut on a chain by turning a handle. A stay is an arm that holds a push-open sash at a set position with no drive mechanism. If your window opens by pushing it and latching an arm, you need a stay, not a winder. A window lock is a separate part again.
Yes — every TradeBase window winder is backed by a 12-year warranty, ships next business day from Australian stock, and can be confirmed for fit before purchase by emailing a photo of the existing winder to sales@tradebaseaustralia.com.au.
You don’t need to know. Almost every Australian awning and casement window built since the 1980s uses the same winder base plate and chain coupling, so the brand on the frame rarely decides the part. What decides it is the hand, the chain length, and whether the winder locks with a key. Work those three out and the replacement swaps straight over without modifying the frame. TradeBase winders replace most Whitco®, Stegbar®, Boral®, Dowell®, Trend®, AWS®, Bradnam’s® and Wideline® winders.
Still not sure?
