Machine Description


Strap-Pak Corners ready to be loaded in Cornermatic PlusThe CORNERMATICPLUS® IG machine will operate with ALL widely available Cornermatic®-type corners and with Mestek Machinery’s revolutionary EZ Connector® corners for “C” and “F” flanges. If you acquire Cornermatic® brand corners from Ductmate, DuroDyne, CL Ward or Mestek Machinery, they will come in the NEW StrapPak™ – 80 corners in a double-strapped package (five (5) packages per carton) to be quickly loaded into the magazine directly from the shipping carton. The StrapPak™ eliminates the need to sort and orient the corners before installation. Other suppliers of Cornermatic®-type corners, such as distributed by Elgen, will not have this unique, time-saving feature.

Universal Corners

Ductmate, DuroDyne, CL Ward and Mestek Machinery also can supply a ”Universal” corner – useable in all TDC® and TDF® flanges. The “Universal” corner has narrower legs and a wider mouth to assist crimping in heavier gages when the flange or Pittsburgh may be distorted. These same “Universal” corners are available for the Mestek Machinery Combination seam closing/corner insertion machine. Genuine Cornermatic® and EZ Connector® corners and LOCKFORMER TDC® and TDF® machines and Pittsburgh roll formers will yield the best results in producing fittings conforming to SMACNA’s Duct Construction Standards®.
