J-Channel Cutter

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.
