The Mark IV Industrial TrimMaster featuring new Power Lock™ Bar and POWERslot™ technology, provide easy setup and operation in the shop and on the job site. Non-marring vinyl strips protect metal finishes leaving clean crisp bends and hems. Our unique cam-locking system clamps to the thickness of the material and not to a factory preset. Should you ever need to fine-tune your brake, each casting comes with independently adjustable UHMW plastic wedges. While some brake manufacturers have taken away your ability to make these adjustments, its nice to know TrimMaster gives you the choice, even if you never have to use it.
