Rated 4.5 out of 5 by 2 reviewers.
Rated 5 out of 5 by Easy to install, secre! I picked up this product from the store. Very easy to install. Instructions were clear. Very easy fix for my security issue! I have an unusual set of doors with the 4 panels. The 2 outboard (for lack of a better word) are inside mounted sliding doors; the two inboard doors are outside mounted doors. The instructions had a simple solution to secure all 4 doors with 2 locks. Love this product!! April 25, 2014
Rated 4 out of 5 by They met our needs. We purchased these to use as improvised window locks. They worked great, although we did have to buy longer screws for a secure installation. February 28, 2013
