TradeBase Buying Guide
Choose the right window lock in 60 seconds
Sash, cam, sliding latch, mini push-bolt. Aluminium and timber compatible. All multi-packs keyed alike. Tiered trade pricing on every listing — buy more, save more.
Window locks aren’t all the same product. The lock you fit to a vertical-sliding double-hung sash is mechanically different from the cam lock on a horizontal slider, which is different again from the latch keeper on an aluminium awning. And there’s a fourth option — the mini push-bolt — that fits any window or door regardless of frame. Get the type wrong and the lock won’t engage. This guide walks you through every decision in the right order so you order the right lock the first time. Already know what you need? Jump to our full window lock range.

The 60-second decision
- What type of window? Double-hung sash, horizontal slider, cam-locked sliding, or universal push-bolt.
- Frame material — aluminium or timber? Mounting holes and base plate dimensions differ.
- What colour? White, black, silver/grey, or chrome.
- How many? Single, 4-pack, or 10-pack — all multi-packs keyed alike, with tiered trade pricing.
1. What type of window?
Sash double-hung
Top sash slides up or bottom slides down. Lock screws to the top of the bottom sash with a keeper-snib catching the upper sash. Most common heritage and timber-frame window in Australia.
Cam lock
A rotating cam swings into a strike to lock. Mounts vertical or horizontal. Best choice for large, wide and heavy sashes — fit one cam at each end so the window is restrained at both points, not just the centre. Common on aluminium-framed kitchens and bedrooms built post-1980 and on big picture-window slider runs.
Sliding latch
Pull-handle latch that catches when the slider closes. Used on aluminium sliding windows where the original hardware is corroded or broken — replaces most generic Australian sliding-window catches.
Mini push-bolt
Universal-fit keyed bolt — works on any window or door, any frame material. Keyed alike across multi-packs. Sash window child-safety, French doors, screen doors, caravans. See the section below ↓
2. Aluminium or timber frame?
The lock body is the same shape but the keeper plate (the bit that catches the snib) differs between aluminium-window and timber-window versions of the sash double-hung lock. Get the right one and the screws go straight into the existing holes.
Aluminium frame · Narrow keeper plate
Aluminium Sash Lock — White
Narrow keeper plate matches the slim profile of aluminium sashes. Screw pattern aligns with most Australian aluminium double-hung windows. Also in Black.
Timber frame · Wide keeper plate
Timber Sash Lock — White
Wider keeper plate spreads load across timber sash. Direct fit on heritage timber double-hungs. Also in Black, Silver/Grey, Chrome.
Cam locks & mini push-bolts are universal — the same body fits both aluminium and timber.
The cam lock alternative — for big, wide, heavy windows
Cam lock · Black
Cam Lock — Sash Double-Hung, Black
Rotating cam swings into the strike, mounts vertical or horizontal. The right call for large, wide and heavy windows — on big sliders and oversized sashes a single centre snib leaves both ends free to rattle, flex or be levered. Fit a cam lock at each end of the sash and the window is restrained along its full width: no flex, no movement, no weak point an intruder can pry. Also suits aluminium-framed sliders and double-hungs where a slim profile is preferred over a snib-style sash lock. Universal fit (works on aluminium and timber), no key.
Rule of thumb: any sash wider than ~1200 mm or noticeably heavy (laminate or double-glazed glass) should have two cam locks — one at each end. Single-point centre locks on big sashes lever open, rattle in wind, and never seat properly over time.
3. The mini push-bolt — universal window & door lock, keyed alike
The mini push-bolt is the swiss-army option in this guide. It works on any window or door regardless of frame material, fits in 5 minutes with two screws on the sash and two on the strike plate, and every multi-pack ships keyed alike to a single key. It’s not a forced-entry security lock — it’s a keyed second-point lock for child safety, convenience, and as a deterrent.
Best uses on windows:
- Sash window child-safety restrictor — bolt limits how far the sash can open
- Sliding aluminium windows — secondary lock above the main snib
- Awning & casement windows — holds the window open or shut at a set position
- Caravan, granny flat, shed — cheap basic locking
- French doors & screen doors — one bolt top and bottom
Choose colour and quantity — all multi-packs keyed alike
Silver Grey

What it gets called — the same part, different names
Window fabricators, glaziers, locksmiths and the hardware aisle all use different words for the same part, so the name on the job sheet often isn’t the name on the packet. If you learned on one system and you’re buying against another, this is the translation.
| What we call it | Also known as |
|---|---|
| Window lock | Window latch lock, sash lock, keyed window lock, window bolt, window catch lock, child safety window lock, window security lock |
| Sash | Window panel, moving pane, slider, opening sash, leaf |
| Catch | Window catch, sash fastener, cam latch, snib, window snib, fitch catch |
| Restrictor | Window restrictor, opening limiter, safety stay, restrictor cable, window chain restrictor, limit stay |
| Sliding window lock | Slide lock, track lock, wedge lock, screw-down lock, sash stop |
| Awning / casement window lock | Chainwinder lock, lockable winder, stay lock, folding stay lock |
| Strike | Strike plate, keeper, receiver, striker, keep |
| Cylinder | Key barrel, lock barrel, window cylinder, lock cylinder |
| Keyed alike | Same key, common key, KA, one-key system |
| Sliding / double-hung / awning | Slider / sash window / top-hung window |
A window lock is not a window winder. A window winder is the geared handle that pushes an awning or casement sash open. A window lock does the opposite job — it stops a sash being opened, or restricts how far it opens.
A lock is not a restrictor. A lock secures the window shut; a restrictor limits how far it opens while still letting the window ventilate. As general guidance, under the National Construction Code an openable window in a bedroom more than 2 m above the surface beneath generally has to be restricted so the opening will not pass a 125 mm sphere, or be fitted with a compliant screen. If your window is in that situation, a restrictor is what’s required — not just a lock. Confirm the detail against the current NCC provisions applying to your build.

Installation
Window-lock installation is straightforward — two screws hold the lock body to the sash, two more hold the keeper. 5–10 minutes per window with a Phillips-head screwdriver. The keyed-alike multi-packs save time on whole-house jobs because there’s only one key to manage. Mini push-bolts are even faster — 5 minutes per window, two screws on the sash and two on the strike plate.

Window lock FAQ
Start with the window, not the lock. A vertical-sliding double-hung sash takes a sash lock, which screws to the top of the bottom sash with a keeper catching the upper sash. A horizontal slider, or a large heavy sash, takes a cam lock, where a rotating cam swings into a strike. An aluminium sliding window with corroded or broken original hardware takes a sliding latch. If none of those suit, the mini push-bolt fits any window or door regardless of frame material. Get the type wrong and the lock will not engage.
Match it to your frame material, because the keeper plate differs. The aluminium version has a narrow keeper plate that suits the slim profile of aluminium sashes, and its screw pattern aligns with most Australian aluminium double-hung windows. The timber version has a wider keeper plate that spreads the load across a timber sash and is a direct fit on heritage timber double-hungs. The lock body itself is the same shape either way. Cam locks and mini push-bolts are universal and fit both aluminium and timber.
Yes. TradeBase window locks are direct mechanical replacements for the major Australian window-hardware brands and suit both timber and aluminium frames, including Whitco®, Lockwood®, Stegbar®, Bradnam’s®, AWS®, Trend®, Wideline® and Boral® windows. You still need to choose the correct lock type for the way your window opens, and the correct keeper plate for the frame material. If you are not sure, photograph the existing lock and email it with the frame colour and material to sales@tradebaseaustralia.com.au and we will match the right replacement.
No. Any sash wider than about 1200 mm, or noticeably heavy because it is laminated or double-glazed, should have two cam locks, one at each end. A single centre snib leaves both ends free to rattle, flex or be levered, and it never seats properly over time. With a cam lock at each end the sash is restrained along its full width, so there is no flex, no movement and no weak point to pry. Cam locks mount vertical or horizontal and take no key.
Yes. The 4-pack and 10-pack ship at roughly half the per-unit price of singles, and every multi-pack is keyed alike to one key. A typical Australian home has 8 to 15 window locks, so the 10-pack suits a whole house and the 4-pack suits apartments and units. Tiered trade pricing applies to every window lock listing. Locksmiths, glaziers, builders, strata managers and property maintenance contractors can email sales@tradebaseaustralia.com.au with typical monthly volumes for set rates locked in for the year.
Not necessarily, because a lock and a restrictor do different jobs. A lock secures the sash shut, while a restrictor limits how far it opens so the window can still ventilate. As general guidance, under the National Construction Code an openable bedroom window more than 2 m above the surface beneath generally has to be restricted so the opening will not pass a 125 mm sphere, or be fitted with a compliant screen. If your window is in that situation a restrictor is what is required, not just a lock. Confirm the detail against the current NCC provisions for your build.
About 5 to 10 minutes per window with a Phillips-head screwdriver. Two screws hold the lock body to the sash and two more hold the keeper. Mini push-bolts are faster again at around 5 minutes, with two screws on the sash and two on the strike plate. Keyed-alike multi-packs save more time on whole-house jobs because there is only one key to manage, and choosing the correct keeper plate for your frame material means the screws generally go straight into the existing holes.
