SPECIAL SIZE PLASTIC DIVIDERS: 14" - 18" high dividers are made to replace the divider that comes standard with the cage. All dividers are punched around the perimeter of the sheet to allow attachment to the wire with C-rings, which are included with the dividers. CRP C-Ring pliers make installation easier and can be ordered separately. When ordering dividers, state cage size you will be installing them in. All sizes, up to 36” long, are the same price.
