Works better than the parking lot and don’t have to worry about it no more
The door lock thing works great slide lock whatever you call it. The fun part is getting the old one out that was broken.

Great Quality and Fast Weekend Shipping
I usually order wholesale parts when I need them, but this Prime-Line J 4516 Aluminum Diecast Flush Mount Extension Bolt was just as good in quality and arrived much faster when ordered on the weekend. The build is sturdy, and it functions just as expected.If you need a reliable extension bolt and don’t want to wait for a bulk order, this is a great option. I’d definitely order again when in a pinch.

Junk
Until now I never would have thought a commercial door hardware item could be made this incredibly cheap.As a professional door and hardware tech for over 40 years I know what I am talking about. For anyone any less qualified than myself the installation would be next to impossible. Modifications must be made to install. I will not use this over priced junk ever again.
