This short insert shows how to use the Miter Shear on the Nu-Glaze glazing gasket to speed up the cutting process and guarantee an accurate, clean cut. The blade can be replaced with ordinary utility knife blade. Most important – keep fingers and other body parts away + the profile must lie flat on shear bed. The middle line must be lined up with mark made, allow for material movement. Practice once or twice to get the hang of it first. Happy glazing!
