The W-series long hand sealers offer a longer sealing length and are ivory in color. These sealers are steel constructed for quality and durability. Round wires can be ordered for cut and seal applications, but the sealers accompanied with a cutter are also available. The blade cuts approximately 3/4 from the seal line. The matching film rollers are available. The manufacturer's replacement kit includes 3 elements and 1 blade if the cutter unit is ordered. Easy to Operate: Simply set the timer, insert the bag between the sealing bar and press down on the seal bar. For the best quality seal, hold the seal bar down a couple of seconds after the light goes off before resealing. For sealers with a sliding cutter, slide across the bag while holding the seal bar down to cut the bag.
