Improvements for lockable handle assemblies
The security plate 50, particularly for use with a lockable handle assembly 100 for a window or door leaf 7, is configured for fixing to an external side 7a of the door leaf underneath a first backplate 30 of the lockable handle assembly such that a perimeter of the security plate fits within that of the first backplate. The security plate may be mounted independently of the backplate, optionally by a plurality of fixings 58 (e.g., tamper-proof screws). The handle assembly may comprise a second backplate 40, mountable on an internal side 7b of the leaf by screws 22 connecting the first and second backplates. The security plate may comprise a bore 54 for a cylinder lock 28. The cylinder lock may comprise an anti-detachment protrusion 60 located behind the security plate in use. The protrusion (in embodiments, a grub screw or set screw) is preferably located in front of a snap line 61 of the cylinder lock.
