## Description

Restore the function and security of older sliding patio doors with this surface-mounted sliding door handle set featuring a hook latch locking mechanism. Commonly found on older patio door systems, this replacement handle mounts to the interior door frame and uses a hook latch that engages a keeper mounted on the jamb for secure operation. Ideal for replacing worn, broken, or missing hardware, this handle set helps extend the life of existing sliding patio doors without the need for costly door replacement. Constructed from durable diecast components with a mill finish, this handle set is built for reliable everyday performance. The interior handle features an extruded aluminum design with a 1-1/8 in. projection from the door frame for comfortable operation, while the low-profile exterior pull provides a clean appearance and convenient access. The integrated hook latch includes an anti-lift feature that helps improve security by reducing the ability to lift the door from its track when locked. Designed for use on compatible sliding patio doors, this handle set features a 3/8 in. latch profile and 4-15/16 in. center-to-center mounting hole spacing. Commonly used by a variety of sliding patio door manufacturers, it offers a dependable replacement solution for many older door systems. Compare the mounting hole spacing, latch profile, and handle style with your existing hardware before purchasing to ensure proper fit.

## Questions & Answers

**Q: How does this fit into a sliding glass door. I use my sliding glass door like a front door. Can we lock / unlock this from the outside?**
A: No.  This lock is designed to attach to the inside edge of the sliding portion of the door.  It is not designed to attach to the facia of the door.

**Q: Need for dementia brother, Is it double sided deadbolt?**
A: No. It goes in the sliding glass door track. It would be quite difficult for a dementia patient to figure out how to use it even if it is not locked with the key. The bolt only goes down when you pull the lever below the lock and visa-versa. It will lock down the door even without using the key. The key is only if you want to be sure the lever cannot be pulled down. The only time I feel a need to lock the deadbolt is if I will be out of town.

**Q: hi i need to purchase a spare set identical to ones purchased recently**
A: I'm not sure what your question is but this product is great. Easy to install and locks up nice and tight.

**Q: Can this be used on an outside panel?  In other words, is the lock corrosion resistant?**
A: It is used on the outside of a patio door that is under cover not exposed to direct moisture. It is not rust resistant.
