Each Trim-A-Slitter comes standard with 4 knives that allow two cuts with each pass.
Ribform
Adds rigidity to your metal with a slightly raised rib. Also helps to eliminate ripples and adds a decorative ‘shadow line’ to wider fascia and frieze board.
Perforate
Optional perforator die sets allow you to perforate 24 gauge steel, .032" aluminum, or copper coil or sheet.DETAILS & SPECIFICATIONS

Most fasteners used in Van Mark tools are standard off-the-shelf nuts & bolts. This was intentional. We use standard fasteners to allow you to get back to work more quickly if something goes missing. Using standard replacement hardware like nuts, bolts & pull-pins will not affect your warranty. For more information, please contact Van Mark directly.
