Sliding Track Lock for Windows, Patio Doors, & Sliding Glass Doors - Pack of 10

These locks are thick and durable, excellent quality. They come with a plastic protector that's easy to put into place and then position and tighten the lock over it. It stays in plays before tightening the screws, a big bonus! Other locks I've tried came with thin plastic tabs that wouldn't stay in place, you had to hold them while tightening the lock. This often required multiple tries and was very challenging when the lock had to be mounted in a position that wasn't super easy to access. Also, buying double locks is well worth it. They're not flimsy and the thumb screws are easy to tighten.

The rubber that keep the door not to be scratch is too thick that you can't fit it all so I need to cut it in half.

package said 10 pc but i received 7 pc.
