## Description

AjustLock 4 Inch Barrel Bolt Lock (Zinc Black)

Review: Perfect! - Easy to install, but had to use old hardware because the screws were too long for what I needed it for. I replaced the locks on my Aussie's wood crate. I love that they have the self adjusting portion, because sometimes they just don't alighn properly die to some previous or manufacturer damage on the door. Perfect for what I needed it for!
Review: Heckin simple - Bought this to lock our patio doors for the washer/dryer room. Installation was simple and the quality was good. After securing the first screw with a drill, I didn't need to worry about possibly stripping the screws. Locks in place. Study. Recommend.
