64mm case, 44mm backset
Ideally suited for French doors
With 2 levers there is little security with this 13mm rebated sashlock - it is however, the best of its class and built to last many years
Predominantly used on rebated French doors, in fact conservatory and summer house manufacturers are the biggest users
Bolt through fixing
On external final exit doors from a house, use a 5-lever lock and rebate kit for security
NOTE: Intumescent should be used to ensure adherence to fire regulations - search for: 'intumescent lock pack'
