Enclosure DividerDivide your 4x2x2 enclosure into two 2x2x2 sides! Removable (Lid needs to be taken off to remove). Easy installation secure divider rails with screws on the inside of your enclosure. Cage NOT included. Temporary divider to separate blocks is a square piece without rails that temporarily screws into a side where two blocks meet. If you want permanent division we recommend getting solid sides for the separate enclosures.
