## Customer Reviews

### ⭐⭐⭐⭐⭐ Works well
*by T***D on March 5, 2023*

I have a heavy wooden front door that doesn’t latch easily. A strong wind would open the door. I replaced the hinges with these, and after adjusting the spring tension, these close and hold the door. I did have to use a much longer Allen wrench because the tiny one that comes with it does not allow nearly enough torque.

### ⭐⭐⭐⭐⭐ Great hinges for a great price
*by S***M on March 24, 2025*

Use them to reach fire code, passed inspections.

### ⭐⭐⭐⭐⭐ It great but you get one, read first.
