Yes I realized that then couldn't edit but with the divider you lose half inch and then you lose another 1 inch in material bc cages are listed with outside dimensions. So 48 - 1.5= 46.5 ÷ 2= 23.25 so that gives you 3/4 of an inch if you mount it on the back wall. If you mounted it so the 22.5 goes width wise of the cage you would only get half inch of room 24 width minus 1 inch in material gives you 23. Animal plastics states that dimensions are exact so you gotta hope they give you exact or more and not less or you will have no room for the 80w. Plus reptile basics says you cannot mount within 6 inches of any surface, I'm sure people do but it will void warranty if you do and something goes wrong. You would probably get away with 4 inches from a surface but you wouldn't be able to mount the 80w even an inch away from a surface.
