HawkTech LC-5005

HawkTech LC-5005 — Pittsburgh Lock Machine for HVAC duct fabrication

The LC-5005 forms the Pittsburgh lock seam on square and rectangular HVAC duct components. With 7 pairs of vertical forming shafts (each with left, middle and right rolls), the profile is formed gradually for a clean, consistent seam. The upper section automatically adapts to sheet thickness via a double-head stud and disc spring — no manual readjustment needed in normal operation. Multiple lock profiles and combinations can be produced (Pittsburgh lock, drive cleat and more).

Compact and light (360 kg) with a small footprint, the machine is easy to move, simple to adjust and reliable — ideal for on-site duct fabrication as well as workshop use in industrial plants, hotels and shopping centres.
