DuroDyne’s Speed Corners is a sheet metal accessory designed to be used in conjunction with J speed flange and standard J flange. They feature tapered coined corner tips for simple hand insertion into the flange, effectively eliminating the need for a tinner’s hammer. Speed Corners are manufactured from 12-gauge steel but are also available in specialty metals upon request. They feature opposing size alignment holes for aligning flange or optionally making connections using a standard 10 ¾ ProPoint screw. Speed Corners meet SMACNA rigidity class J as used in conjunction with Dyn-O-Mate J Flange or J SpeedFlange.
