Using a KF-150 series handheld sealer and want to upgrade to a hands-free direct heat sealer?Rather than upgrading to a more expensive machine, consider using the PC-Set pedal and clamp set. The set consists of a mount for the T-clamp heat sealer that attaches to a table with a chain that leads down to a foot pedal. The chain can be adjusted to accommodate the height of the table. Once in place, this handy set makes it easy to use your foot, rather than your hands, to begin heat sealing film and bags. Affordable and simple attachment!
