This collection contains high-quality sliding door mortise locks for patio doors, which are superior to other types of door locks because they can offer increased security and privacy. The unique design requires a mortise to be cut into the door, into which the lock assembly is inserted, producing a sleek look which doesn’t show any hardware from the outside of the door. There are two main types: Single hook locks and two point mortise locks. We carry Truth Hardware mortise locks, Roto, Interlock, Gemini locks, PGT, Giesse and much much more. Please contact us if you need assistance in selecting the correct mortise lock for your door.
