Use a versatile Malco Redline 5/8" J-Channel Cutter (JCCR) to make drain tabs, downstream notch cutouts and miter trim cuts in vinyl channel. Tool operation is fast and easy! Light hand pressure produces a single handle click signal to ensure perfect drain tabs every time. Graduations on the upper jaw easily gauge tab or notch depths from 3/8 to 1-1/4 in. (9.5 – 31.2 mm). Use either side of the jaws to cut a 45-degree miter for a professional finished look. Hardened all-steel construction with rust resistant nickel chrome and black oxide finishes ensures long service life.
