The Malco SL1R Snap Lock Punch creates raised, louver-shaped projections along sheet metal edges for fabricating rectangular ductwork. The punched edge locks into a rolled edge, allowing sheet metal pieces to snap together for a secure connection.

A heavy forged cutting jaw with rust-resistant plating and a black oxide finish is built for dependable use on the job.
