Window locks: double hung sash, cam and sliding window locks

The right window lock depends on how the window opens. The Window Lock Buying Guide gets you to the right product in four questions.

• Double hung sash windows: use a sash lock, either the narrow keeper for aluminium or the wide keeper for timber.
• Large or heavy windows: use a cam lock.
• Sliding windows: use a sliding window latch.
• Any window or door: the universal mini push-bolt fits most.

Our 4-pack and 10-pack locks ship keyed alike, so one key opens every window. Window locks are direct replacements for Whitco®, Lockwood®, Stegbar®, Bradnam’s®, AWS®, Trend®, Wideline® and Boral® window hardware. Replacing a winder too? See window winders.
