Oh dude. I just noticed too, that was my first shower surround cage. I have totally revamped it and that hardware sucked. I have found some much nice looking twist locks and hinges.
Here is a more updated idea of what they look like now...Sometime after this photo was taken, painted all the hinges white too.
This is a little 2 foot cage
and this is a double arboreal cage. It's one unit but two seperate cages. I made them this way (4' x 20" x20" total 24" x 20" x20" each side) to make them stackable with other 4 foot cages. I cut the vent holes with a 4 inch hole saw which just happens to work out that you can plug the ones you don't want open with deli cup lids
