Quad Corners

There are many different flanges used in “Four Bolt Connection Systems” and each one has a corner designed especially for use with that flange. This makes stocking material for each system complicated and often confusing. Also, the physical design of many corners often requires their manufacture from heavy gage steel. The Dyn-O-Mate Quad Corner is a versatile corner for use in Dyn-O-Mate J as well as many other flanges. The unique design of this corner results in performance like that expected from heavier gage, but at a lower cost.

• Compatible with Dyn-O-Mate™ J, Ductmate™ 35, CL Ward™ J, Ward Industries™ J, and Hardcast flanges.
• Quad corners are manufactured from 16-gauge steel, aluminum or stainless steel.
