J-Channel Cutter

4.5 of 5 stars


Use a versatile Malco J-Channel Cutter to make drain tabs, downstream notch cutouts and miter trim cuts in vinyl channel. Available in three sizes for 1/2 inch (12.7 mm) channel, 5/8 inch (15.9 mm) channel and 3/4 inch (19.1 mm) 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.

Malco J-Channel Cutters also feature ergonomic RedLine Handle technology. An Engineered handle opening compliments the natural power stroke of any user’s hand and maximizes the powerful 7:1 mechanical advantage of compound-leverage head to handle linkage. Comfortable handle grip contours, a non-slip grip insert, spring handle actuation and a thumb-operated handle latch ensure a natural fit and feel for comfortable one hand operation anywhere on the job.
