Frequently Asked Questions

What types of window locks do you stock?

We stock a wide range of window locks including sash locks for double-hung windows, casement locks for side-hung windows, sliding window locks, and cable locks such as the REMSAFE range for child safety and security. Available in white, chrome, and other finishes to suit most window frame types.

What is a window restrictor and do I need one?

A window restrictor limits how far a window can open, typically to 100mm or less, to prevent children from falling. They are required under Australian building regulations (NCC) for windows in certain locations, particularly above ground floor in residential buildings. We stock cable and chain-style restrictors suitable for most window types.

What window hardware suits aluminium windows?

Most of our window locks, stays, and handles are compatible with aluminium frames. Look for products specifically labelled for aluminium or universal fit. Friction stays and inline handles are commonly used on aluminium casement and awning windows. Our team can help match the right hardware to your frame type.

What is the difference between a window stay and a window restrictor?

A window stay holds a window open at a chosen position for ventilation and can be adjusted or released freely. A window restrictor limits the maximum opening to a fixed distance (typically 100mm) for safety purposes and requires a key or tool to override. Both can be used together for ventilation with child safety compliance.

Do you stock window hardware in black or heritage finishes?

Yes. We carry window handles, stays, and fasteners in a range of finishes including white, chrome, satin nickel, and black. Heritage and period-style fittings are available for timber sash windows. Contact us if you're looking for a specific finish or style to match existing joinery.
