As the description implies, a mortice lock is morticed into the door.
Choosing and fitting a LockGuard to a door fitted with a 'standard' mortice deadlock is relatively straightforward and Kickstop supplies the largest selection of LockGuard plates available for this purpose.
A sashlock generally requires more wood to be removed than a deadlock and has an additional hole drilled through the door for the lock spindle to pass through.
Kickstop's unique SashlockGuard has reversible offset plates to allow fitting even if the frame has wider door stops and draught excluder.
The elongated apertures in the SashlockGuard plates are designed to accommodate the spindle and keyway/cylinder of most sashlocks.
