Review: I love it! - Worked perfectly! It wasn’t the correct fit but my contractor made it work!
Review: Super Sturdy & Easy to Install! - We purchased these locks to go on the French doors between the main house and our bonus room, and we are very happy with the purchase. They are easy to install, and are very sturdy. It took my husband about 15 minutes to get them on the doors, and the locking mechanism is easy to operate. When the lock is engaged, the doors are secured, and I am not worried about them coming loose in anyway. Overall, we are very happy with this purchase and we would buy these again.
