wanting to make boa enclosure

[Rickys_Reptiles]

ok so hdpe it is if i go that big...to screw together just pre drill and screw like plywood???

Jason is correct... at the size you're making it's bound to have issues if made in PVC. I'd recommend making it out of wood also, perhaps a marine grade ply.

However, if you're dead set in your ways, then do yourself a favor and at the absolute very least, make a support divider. You can make it like this picture so that your snake can still move back and forth.
