Harney Hardware’s sliding patio door bars and sliding window locks add security to any tracked sliding glass door or window.
Sliding patio door bars are screwed into the side of any sliding door. The long bar arm drops into the door track prohibiting door movement. Cut the patio door bar a bit shorter to allow a small opening for ventilation or pets.
Use our aluminum sliding window lock with horizontal sliding windows. The sliding window lock can be positioned along the window track to either lock the window completely shut or allow for partial window opening for ventilation.
