GU 4463 Lockable Concealed Window Restrictor

Description

The GU 4463 lockable concealed window restrictor is a heavy-duty, lockable concealed window restrictor specifically engineered for side-hung windows. Unlike surface-mounted cable restrictors, this unit sits discreetly within the window rebate (the gap between the frame and the sash), providing a clean, invisible finish when the window is closed.

It’s most commonly used in steel window systems (like Crittall) but is also compatible with timber and aluminium frames that have sufficient depth for the arm.
