Secure sash locking – with solid cast zinc construction
Solid cast zinc forms the main body, while a powder-coated surface resists wear and provides a smooth white finish. Mechanical locking relies on a hardened interference arm that prevents sash lifting when engaged.
Firm resistance to forced opening gives extra protection against opportunist entry, and reduces the risk of accidental sash opening around children and pets.
Quick installation – thanks to included fixing screws and simple twist action
Each set includes matching screws and an installation guide, and the interference arm twists into place to lock or release the sash. The screw-fit design attaches directly to PVC-u, wood and composite frames using basic hand tools.
A straightforward DIY fit means minimal fuss for most householders, so security can be upgraded in a single afternoon without specialist tools.
Versatile compatibility – with support for vertical sliding and hung windows
Designed for vertical sliding, single-hung and double-hung vinyl windows, and suitable for many PVC-u and wooden frames and sliding doors. Low-profile footprint leaves the sash operation clear when unlocked.
Works across common window types, making it easy to standardise extra security across multiple rooms and doorways.
