SL2R adjustable Snap lock Punch can be used as a gutter end cap crimper or for use in creating locking tabs in light sheet metals. A slide adjustment for throat depth allows settings from 1/4 to 5/8 inch (6 to 16 mm) depth. The formed metal cutting jaws and handles are made of hardened stampings. Rust resistant nickel plate and black oxide finishes ensure long service life. Easy one-hand operation make this a versatile tool for the job at hand. The SL2R Snap lock Punch also features 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.
