### ⭐⭐⭐⭐⭐ Door loop lock
*by A***R on November 6, 2025*

### ⭐⭐⭐⭐⭐ Feels Secure and Easy to Install
*by M***M on August 8, 2025*

Great value. Purchased after a strong wind blew our double doors open. Feels much more reliable than the old chain lock. Applied in to single and double doors, works well.

### ⭐⭐⭐⭐⭐ GREAT quality, great product
*by L***E on May 24, 2024*

PROS: -got here fast -very high quality -works on in-swing AND OUT-SWING doors CONS: -install is a little tricky if you want the latch to drop in smoothly -screw that come with it are not what you need to properly secure this to the door and frame EXPLANATIONS: I would definitely buy these again. My landlord refused to install deadbolts so I installed these because my front door is in-swing and my back door is out-swing. I wanted something to match but that would also be study like a deadbolt. The key is getting better screws. The screws that came with the prouct are size 6 (diameter) and are one inch long. I was looking for home security, so I got the longest screws I could find based on the width of the frame and the door. In the video, I am putting my whole body wight into opening the door (25F, 210 lbs) and NOTHING. I feel so safe in my house now :) Side note: youre supposed to use size 6 screws but you can use size 8, its just more finicky because they BARELY fit.
