Features of the Cornermatic II Whisper-Loc Combo Automated Corner Insertion and Pittsburgh Seam Closing Machine:
- Designed for ductwork corner insertion and seam closing without having to handle the ductwork between processes
- Pneumatic operation automatically inserts corners into both ends of ductwork that use the transverse duct connection (TDC) or transverse duct flange (TDF) method of joining and crimps them securely and permanently into place in seconds
- Corners are inserted square and fully crimped — no need to change the crimping adjustment when inserting corners in 16 to 26 gauge fittings
- Electric motor and gearbox with variable frequency drive powers the seam closing operation
- Works with SMACNA-conforming, T-25a and T-25b flange and many other flanged duct systems without changing settings
- Will also close the Pittsburgh seam on ductwork that uses the raw edge or slip and drive method as well as slip-on flange type ductwork
