The Harvest Keeper� Impulse Bag Sealer is a premium, heavy-duty-unit that seals bags up to 15 in wide. A convenient dial let�s you quickly adjust seal times from 1 to 10 sec for just about any type or thickness of bag material. Being able to adjust seal times delivers extra safety and consistency, since the heating element stays on ONLY for the time you set on the dial. Creates a seal that is 2 mm wide. In addition, the sturdy sealing arm is mounted on a thick, weighted base with non-slip rubber feet for extreme stability. Includes 5 ft power cord.
