Angle Cutter Guide Used for cutting angles, corners, tags, etc.
This aluminum angle-cutting guide is quick and easy to install. The two clamps attach to the paper cutter's back gauge ribs. (The same way a paper cutter book clamp would attach.) Once it is secured in place it will not slip out of position, as some single clamp guides are prone to do. It is fully adjustable for cutting any angle from 0 to 90 degrees. Once it is set in position on the backgauge, it will allow for repeated cuts at the same angle. It measures 2-5/8" high (67 mm high). A box end wrench is included with each angle guide to aid in installation and adjustment.
