20 Pieces Spring Door Latch for Rabbit Cages Door Metal Finger Spring Latch Hook for Fixing Pet Wire Cage Rabbit Birds Bunny Rodents Guinea Pig Hamster Parrot Hedgehog Cage Door (2.87 x 0.9 Inch)

I built my own cages and needed closures. These were a little difficult at first to figure out how to attach. Once you get the first one though its easy. Highly recommend.

I use this to secure a cage I got to hold kittens in and they work great. I will also use these to secure my doors on my tru catch traps for animal rescue

Better design elsewhere, pull loop separated is easier to use. Difficult to pull this ring to latch.

It works as a replacement for dumor cages
