I ordered a replacement garage lock kit for my 1950s garage - it fit perfectly. I can now open the garage door from outside rather than running though the house. Wonderful!

Intially recieved the wrong key pad, yet contact the company they send out the correct pad before I returned the incorrect one. Truly outstanding service.

Great product. . Arrived in a timely manner. . Very quiet garage closure now!

My son bought a home that had a worn out garage door opener but your parts were the perfect replacement to get things working again. You tube has some great videos on how to install the gear and sproket assembly. Between that and your quality parts he should be set for years to come.

This was just what I needed to open a large overhead door in my pole barn. It fit perfectly and it works great. No more straining my back trying to heave the big door open!!
