About this product
The StanGroup Button Punch Snap Lock-former is a dedicated roll former for the longitudinal seam on rectangular HVAC duct. Duct shops and mechanical contractors like the snap-lock seam because duct halves can be formed and stacked flat, then snapped together at assembly instead of having a seam hammered closed.
The machine forms both sides of the joint. It comes with male and female rolls: one side rolls the pocket, the other rolls the matching edge with a row of punched buttons that catch inside the pocket when the two halves are pushed together. StanGroup lists it for galvanized and stainless steel from 18 to 26 gauge, and mentions aluminum among its applications. Forming speed is 40 ft/min, with 9 roller pairs on each side driven by a 3 HP (2.2 kW) motor. StanGroup’s current page gives the power as 220 V single-phase, 60 Hz.
It is about 60″ long, 26″ wide and 42″ high, and weighs around 980 lb, so plan for a forklift or pallet jack when it arrives.
It suits shops that already build rectangular duct and want snap-lock seams alongside Pittsburgh. For the Pittsburgh lock and hem profiles, see the Pittsburgh Lock Forming Machine. For transverse joints, the S-cleat C-drive locking pin Pittsburgh and Seam Lock Forming Machine forms S cleat and drive cleat. The Square Duct Beading Machine for HVAC stiffens wide panels, and Steel Coil supplies the stock.
It is available from our New Brunswick, NJ warehouse; call (732) 561-4275 to check stock, or add it to your quote.
