ADVANCE Pittsburgh Whisperlock® Seam Closer

Description

Advance AutoFold Duct Seam Overview: The DCS roll-forming machine takes HVAC ductwork that has previously been formed into “L” or Fully Wrapped Duct Sections, ot even large duct that has been fabricated in 4 individual pieces, applies a male and female seam and closes the seam together quickly, quietly and tightly. Basically, a non-seamed section of duct goes in one end and a completely closed seam section of duct comes out the other end. The capacity of the DSC is 26 – 20 gauge.
Specifications for the DSC lock are listed in the SMACNA HVAC Duct Construction Standards, Second Addition, 1995. The DSC lock is referred to as a Double Corner Seam or as a Slide Lock Seam. The male and female allowance of the DSC is similar to that of a male and female Pittsburgh seam. (ACS recommends that you check with your local inspector for the approval of the DCS lock). ACS has many contractors using this seam who will be happy to discuss their satisfaction with it.

The effectiveness of the Duct Seam Closer is enhanced when used in conjunction with the AutoFold Coil Line. The Duct Seam Closer also works well with Ductmate or Ward knock-on-connectors and can also be used with ductwork that already has the Drive Clear edge turned over. (The Duct Seam Closer does not work with the pre-insulated ductwork or TDC® or TDF® duct connectors).
