Clips over front of tubs to prevent tubs from being pushed out of the rack – to prevent reptiles from escaping. On multi-tub levels (2 or more) a large clip can be used (if placed between two tubs) to lock two tubs with one clip. Standard size should be placed on the front-center of each tub to securely lock.
IMPORTANT: If your rack utilizes plastic ventilation clips (rather than the classic embossed metal vent clips), these clips will not fit properly over the new plastic vent clips due to the increased thickness of the plastic. They will still work to lock the tubs shut, but do not sit flush with the plastic vent clips.
