Whisper-Loc Seam Closer

One. Product description

1. Whisper-Loc Seam Closer are available in the horizontal or vertical and close Pittsburgh seams. Vertical whisper- Loc seam closer is what highly recommend. Pittsburgh joint is commonly used to join the seams of metal ducts. Seam closing has traditionally bnacomplished by manually hammering the margin of the seam against the duct wall (peening). Disadvantages of such peening include the time required and almost intolerable noise produced.
2. The latest desigh in seaming technology is now available. At the Pittsburgh joint, the individual seams are called Pittsburgh seam ( Pittsburgh lock) and standing seam (right angle lock). On a Pittsburgh joint, the operator pushes the standing seam into the Pittsburgh seam, fastens them to each other and closes the joint on a seam machine.

Generally, three different seams are common in the industry to connect the corners of the ducts: button lock seam, Pittsburgh seam and Duct seam.
