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

5. Trade pricing — tiered on every listing
💰 Trade pricing applies to every window lock.

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.
