I'm going to build me my own custom racks out of 1"x1" thin wall tubing for all of my racks from hatchling to juvenile to adult. I'm going to start building them for people if they want me to. I will build them to your specifications and to fit whatever tubs you use. I'm not looking to make a living out of it, just want people to have a quality and safe rack for their animals. I might even think about building vision cages. what do y'all think? Also, all will include casters if the customer decides they want it portable or stationary. It will have pre-drilled holes for the wheels.
