Just in case you look here first
here's a copy paste of my same post in your other GTP one..
to add a note, you want to get them installed in a way they are easy to remove, this will be of great help when cleaning or getting the GTP off the perch.. since turning it slowly to coax it off is the best way to avoid a bite
sorry !! i missed that post in the enclosure section
here's a few ways of doing it.. the first two are good for bigger cages but will work well for a small..
this first one is a bracket i made out of xpvc and then siliconed to the glass, then you simply groove the end of the perch so it slides in .. this prevents it from turning.
this second way is made with closet pole brackets found at any hardware store. silicone in place, the other end is half open so the perch sits on it. the problem with this set up is that the perches can turn on themselves !!! you need to either drill a hole and get a tie wrap in it or black electrical tape.. tape is not the best but it works, and the reason for the electrical tape is that is for ever reason it comes in contact with the snake !!! it doesn't stick to it much at all, if at all..
now the third way od doing it , and i think this might be the easiest for you and simplest, it works well and for a small light weight GTP would be perfect.. I don't have a picture of this but will try to explain..
you can get suction cups (big ones) and (small ones) with plastic hooks on them. these actually hold on quite well for a long time..
just drill little holes on the end of your perches and screw in O- shapped latch lock part on each end and hang it there..
if your are worried or see that it comes off when the snake moves or is excited feeding time, secure it with tape or tie wrap.. they are fairly tight once installed but !! sometimes they can get loose..
hope this helps
