These sides will fit any XL cabinet. They will also work on any Blue or Classic Maxx cabinet. The sides are brand new, machine cut out from the same material of which the originals were constructed. They have the same threaded inserts as the originals. You will have to use your exisiting bolts and rails, although you will NOT have to drill any holes. The only thing you will need to put these on is a Philips head screwdriver.
