Bought two lockable slam latches for both end doors of my 400 collapsible crate. Very quick and easy to install the latches. I like to have the ability to lock my dog's crate at large dog sport events if I choose to do so without having to carry padlocks.
So glad I got this. Works great and No more worries.
Stainless Steel Locking Slam Latch
Love it, it keeps Telly in and others out. Great service!
