2-point double hook sliding door locks are specialized security components designed to strengthen sliding patio and glass doors by engaging two steel hooks into the frame. Unlike single-hook or latch mechanisms, these double hook locks offer improved resistance to prying and forced entry, making them a highly trusted option for both new installations and replacements in homes, apartments, and businesses.

How Double Hook Sliding Door Locks Work

Double hook mortise locks use a dual-hook system that extends deep into the door jamb when the lock is engaged. This mechanism significantly increases security by anchoring the door at two separate points. Many models, like our face plate door lock, feature an anti-slam pin, ensuring the hooks only activate when the door is properly closed. This not only protects the lock hardware but also extends the life of your sliding door system.

Use Cases & Compatibility

These double sliding door locks are ideal for replacing worn or damaged locks on wood or vinyl patio doors, as well as for upgrading from older style sliding door locks to newer, more secure models. They are commonly used on leading brands of sliding glass and patio doors that require a 2-point double hook mortise mechanism. Typical applications include residential patios, apartment entries, and commercial glass doors. For example, the mortise lock for sliding patio doors is compatible with many standard door profiles used by door manufacturers across North America.

Installation & Replacement Tips

Installation is straightforward for anyone with basic DIY skills. Before ordering, carefully measure the face plate length, backset, and mounting hole spacing to ensure compatibility with your door. Many locks, like the 2-point double hook lock with no faceplate, can directly replace older models. Always retain original mounting screws, as not all lock kits include new fasteners. Adjusting the hooks or actuator may require a Torx T-10 driver. If your existing lock has an anti-slam pin, confirm that your replacement offers this feature for continued protection.
