Handy accessory to double your available rack space. A simple three piece design allows for easy installation and removal for cleaning. Cuts the Sweater box 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 chlorhexadine solution for maximum life of the product. Not for use with very small snakes (freshly hatched corns, etc.).
