help with mounting perches

[rebel_logan_24]

so i found a really good deal on some decorative bamboo that im gonna use in my carpets new enclosure im building. the only problem is that i can figure out how to mount them. they are about 3" shorter than the width of the enclosure and the ends of the bamboo are hollow so it make a hook and eyelet idea kind of hard. basically looking for any ways to mount them but not make it look obvious due to the fact that its a display enclosure. but as long as i can cover it with some fake plants and the perch wont swing or move a lot i am open to ideas thanks Logan
