A keeper — sometimes called a striker plate or lock receiver — is the small but critical component that your sliding door bolt or lock engages with to hold the door securely closed. When a keeper wears out, gets knocked out of alignment, or breaks, the door will feel loose, rattle in its frame, or fail to lock entirely. Slide Master Hardware stocks a comprehensive range of keepers and cylinders to suit aluminium sliding doors and windows across a wide variety of Australian-made frames.

We carry keepers to suit popular door and window systems including those from Stegbar, Dowell, Jason Windows, Trimview, and Precision. Because keeper profiles vary considerably between manufacturers — even between different production runs from the same brand — correct identification is essential before ordering. Our team at the Wangara store is experienced at matching keepers from photos, so if you’re not sure of your exact model, send us an image and we’ll identify it for you.

Cylinders for sliding door locks are also available, including replacement barrel cylinders where the locking mechanism itself has seized or been damaged. A cylinder that won’t turn is a common problem in coastal Perth suburbs where salt air accelerates corrosion inside the lock body — replacement is usually more economical than attempting to free a corroded barrel.

If you’re finding that your lock engages but the door still feels loose, the issue is often a worn keeper rather than the lock itself. Browse our full range of sliding door handles and locks to find the matching lock set, or check our fly screen and barrier door parts if the keeper is on a security screen rather than the main door.
