The SealerSales WN-900C 35" Foot Sealer w/ Sliding Cutter and 2.7mm Seal Width can seal 15-20 bags per minute while allowing you to keep your hands free for faster and more precise sealing. It has a 26" steel frame for added safety and stability, a height-adjustable working plate, a manufacturer's replacement kit with two elements, and an optional round element for seal and cut applications. To use, simply set the timer. Place the bag between the two sealing bars and press the footboard down. After the timer goes off, hold down the footboard for another 2-3 seconds to set the seal. This sealer is ideal for high volume, extra-long sealing.
