2 Point Sliding Door Locks | Dual Point Mortise Locks for Wood & Vinyl Doors | AmesburyTruth Parts

2 point locks, also known as 2 point mortise locks or dual point locks, are designed for sliding patio doors that require enhanced security and stability. By engaging two locking points,typically at the top and bottom of the door,these locks prevent forced entry and minimize door flexing, which can otherwise compromise the weather seal or allow the panel to lift off the track.

Where 2 Point Locks Are Used

These locks are commonly used on wood, vinyl, aluminum, and composite sliding doors in homes, apartments, and light commercial buildings. A popular example is the Gemini 2-point double hook sliding door lock, which includes anti-slam technology that protects both the hardware and your door by ensuring hooks only engage when the door is fully closed.

Choosing and Installing Replacement 2 Point Locks

When replacing a two point lock, match your existing door's faceplate size, lock body depth, and screw hole spacing for a direct fit. Most locks in this collection are original AmesburyTruth hardware, ensuring compatibility with many popular window and patio door brands. These mortise locks are ideal replacements for sliding doors that have become loose, difficult to lock, or have worn-out security features.

Installation typically involves removing the existing lock by unscrewing the faceplate, sliding out the old lock body, and reversing the process to install the new unit. Precision is key,always confirm measurements and compare them to the product specifications. For added security or to repair a worn strike plate, consider using a compatible strike plate or updating the faceplate with a long stainless steel trimplate or a short zinc dichromate face plate designed for your lock model.
