The Surelock McGill range comprise lockable handles that provide key entry provision for doors fitted with Surelock panic and emergency exit devices. The internal panic bar, emergency exit lever handle or push pad will override the locked handle and release the bolting device.

The range includes LEO’s that can be surface mounted and, for higher security, LEO’s that can be recessed into the door. The more recent designs incorporate a Euro-profile cylinder, this enables cylinder change-over to be made between different makes of cylinders.
