The Heavy Duty Trainer Kit is our Easy Dog Panel assembly. In a few minutes you can have your Heavy Duty Dog Door act as an Easy Dog Door to help acclimate dogs to the dog door concept or when converting to a Gun Dog House Door product.
The dog door panel replacement can also be used for whelping rooms during those transitioning weeks when the pups are learning to go outside.
The Heavy Duty Trainer's dog flap door panel bolts directly to the Heavy Duty Dog Door so no additional hardware is needed.
Put your regular spring hinge assembly back on when the weather turns warmer/cooler and you want to save money on your energy bill.
