Bought as replacement for a lock that had worked for 30 years; hopefully this will work as long. Quality of construction great; details held on the Safe site really helpful in identifying the correct replacement (the old lock was unbranded but is obviously exactly the same model). Extra keys cut by Safe and deleivery all as expected - fitting into the existing cut out was no problem at all. The level of dimensional detail held on the Safe site really helped and the supplied product met all expectations. Would definitely buy from Safe again in future - the prices were right too.

Hello - when it says, use with a left hand hung door. Is that looking from the outside of the house or inside looking out?
Edward Evans, Southsea
When trying to determine if you need a left or a right handed door lock, stand on the outside of the door. If the lock is on the left, you need a left handed lock. If the lock is on the right, you need a right handed lock.
