Product description

The Norlok Surelok II 13 24V HS is a floor-mounted clinching machine designed for the HVAC fitting industry and large-volume fitting manufacturers. It forms a Clinchlok joint — the upper tooling squeezes two plies of sheet metal between a punch and die, locking them together with no rivets, bolts, fasteners, heat or adhesives, no fumes, and little or no damage to painted or galvanized finishes.

Built on a solid 3-inch (76 mm) steel C-frame with a WAMP pneumatic power unit, regulator and shut-off valve, the machine is foot-pedal operated and runs at up to 150 cycles a minute at a 3/8-inch stroke — 2-1/2 clinches per second, the fastest OSHA-safe clinching. The 24V high-speed electronic option can be switched on or off, and the adjustable Anti Fatigue auto cycle runs from 400 ms to 3 seconds.
