The X-Large forever insert divider is a practical kennel divider for our X-Large Tucker Murphy Pet™ G3 kennels. The forever insert divider is ideal for puppies as it makes our full-size kennels smaller with the ability to adjust the kennel size as the dog grows into the kennel. The divider comes in two halves to easily fit through the kennel door. The quick and easy installation uses existing kennel vent holes and rubber grommets to keep the kennel divider locked in place.
