The heavy duty bag taper has a 5/8" wide throat used for sealing heavy mil bags. With a built in trimmer, the all steel bag tapers are available in red and offer a sturdy base, with pre-drilled holes for mounting the taper to a work surface. The all steel bag taper uses 3/8" and 5/8" tape which is inserted on a rotating wheel which automatically replenishes itself every time a bag is properly sealed. One free roll of tape is available with every dispenser. Take a look at the step by step procedure below on how to use the bag tape dispenser.
