The quiet, automated way to close Pittsburgh seams in less than six seconds!
Eliminate hammering to close ductwork, large and small Pittsburgh seams, greatly reduce noise levels and speed up duct seam closing in your shop or at the job site. Whisper-Loc will also close both insulated and reinforced ductwork.
The IPI Whisper-Loc features a mircoprocesser with push button controls to allow the top closing station powered head to be moved quickly to facilitate changing duct lengths. The machine features adjustable material clamps and side block adjustment.
The machine operates with any cross section joint, ie. TDC/F, Slip and Drive, Raw Edge, or Slip on Flange.
