Everyone ask that same question when they first hear this name.
Well, a Billy Button is about the best way to lock a glass sliding door. Once installed the door stays put, it will not lift, will not slide. As you can see from the pictures the lock is small and out of the way. Factually the door is screwed to the frame. Billy buttons prevent the bypassing of the standard locks on your sliding glass doors.
An added benefit of having these locks installed is you are protecting your children from opening the doors and falling into the pool or wandering off.
Billy buttons are the most cost effective way of securing your sliding glass doors and protecting your family.
