Snap Lock Punch for Vinyl Siding

The SL8R Snap Lock Punch for Vinyl Siding produces wider, more prominent rectangular tab projections for securing vinyl skirting or siding to finishing trim.  The raised tabs grip a greater surface area and guard against dislodging due to relaxation of vinyl from heat or blowout during times of high pressure and wind. Constructed of hardened steel stampings and rugged investment cast alloy steel jaws with rust-resistant nickel plate and black oxide finishes to ensure long service life.

The Malco SL8R 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 anywhere on the job.

Attention: For use with vinyl only. Not recommended for use below 32° F (0° C)
