Iowa Precision Cornermatic Plus


In StockReady To Ship

The CORNERMATIC PLUS® was specifically designed to address the difficulty with inserting corners into some styles of fitting ductwork. It joins other world- wide successful Cornermatics such as the Dual-Head and the Corner Cadet® in reducing shop labor. Three years in development brings to the trade a machine that can handle any TDC®/TDF® fitting assembled on a bench. The CORNER- MATIC PLUS® automatically and effortlessly inserts and crimps TDC®/TDF® corners in seconds. Lets you do a duct section (eight corners) in about 20 seconds in any gauge, 16 through 26. Generally, tests have shown 80 ducts/hour vs. 15 ducts/hour for manual insertion.
