## Description

Review: Good Quality - These are easy to mount and come with sturdy, aelf tapping screws. Well worth it.
Review: 10/10 recommend! - I got these to lock our garage with extra security whenever we leave on trips. I am a big fan! It def provides extra security when they’re locked- the garage will not open at all!! We installed 2 on the big door that faces the alley and there’s 1 installed on the smaller door we have facing our backyard. I think 1 in each garage door will work on its own! The design is perfect because the holes + spot on your garage door is already set up for these. Installation was very fast and easy. They fit perfectly and they’re built very well. Great value for the price paid!! Would recommend this item.
