Review: Door loop lock - I like to secure my screen door at night so I bought this amazing and easy to use lock. Is easy to install and work perfect for the door. Highly recommend
Review: The extra measure you need - Aside from the tool criminals use to gently shatter your whole glass, this little lock gives you that extra minute to go grab a defensive tool after they crowbar the latch lock open. Our house is like Fort Knox except for a stick in the sliding door, which isn't "always in" due to bending over etc. Not the most decorative piece but we put it higher up. You can put this anywhere, even on a molding frame that isn't flat, just use longer nails for stability.

### ⭐⭐⭐⭐⭐ The extra measure you need
*by W***R on March 9, 2026*

Aside from the tool criminals use to gently shatter your whole glass, this little lock gives you that extra minute to go grab a defensive tool after they crowbar the latch lock open.

### ⭐⭐⭐⭐⭐ Great for ANY door!!
*by D***3 on September 26, 2023*

I’m using this on my storm door as extra reinforcement so my special needs teenager can’t wear down the handle lock or push the door open and run out (like he did on my mother’s door, and so outsiders can’t rip the door open and get in. This is very strong, easy to install and easy to use. I’m 50, female, and it took me less than 10 minutes to get my drill and install this lock. I marked the holes on the frame with a pen, pre-drilled the holes with a drill bit and then drilled the screws in. It’s very secure in both the frame and the door, and I’m very happy with this product! I was not compensated in any way for my review.
