This CORNERMATIC® 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 either (i) oriented and stacked in the shipping carton (250 corner pieces per carton) for quick and easy loading into the 175 corner magazines feeding the top and bottom crimping heads, or (ii) 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 will not have this unique, time-saving feature which eliminates the need to hand-load the corners before installation.

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.  Genuine Cornermatic® and EZ Connector® corners and LOCKFORMER TDC® and TDF® and Pittsburgh roll formers will yield the best results in producing fittings conforming to SMACNA’s Duct Construction Standards®.
