Whisper-loc Seam Closer

TRS-1 Vertical type whisper-loc sean closing machine
Pittsburgh type lock joints are commonly used to join the seams of metal 
ducts, whether the sections are rectilinear, tapered or rounded. In all
these types, seam closing has traditionally been accomplished by manually
hammering the margin of the seam against the duct wall (peening). 
Disadvantages of such peening include the time required and the almost 
intolerable noise produced.
The TARGE Whisper-Loc Seam Closer (Pittsburgh Seam Closer) locks the 
pittsburgh seam automaticly of ducts.
