Handy accessory to double your available rack space. A simple three piece design allows for easy installation and removal for cleaning. Cuts the CB-70 bin evenly in half lengthwise. Allows viewing tub contents on both sides. Made of thick, sturdy plastic to avoid escapes or crossovers. Can be easily and effectively sterilized with a light bleach solution or we recommend a f10 solution for maximum life of the product. Not for use with very small snakes (freshly hatched corns, etc.).
