Two standard hex Mega-Couplers shown combined to make a 90 degree coupler using the 90 degree plate and hardware kit.

The Mega-Coupler has solid wing nut tabs that are stronger than regular steel wing nuts. The grade 8 Hex Head Cap Screw locks securely into the hex milled pocket so that the nylock nut can be tightened while the clamp is installed

The Mega-Coupler fastens from (1-1/4" Pipe) 1.66" OD to 2 " OD truss tube and has the industry compatible 14 mm thick base.

Although 1/2" is the most frequently used hardware size, the Mega-Coupler also comes in a 3/8" and 1/4" size. Other Mega-Coupler options include stainless steel hardware, steel wing nuts, Metric M-12 and M-10 hardware.

For countersunk Mega-Couplers, see the Flat Head Mega-Coupler section.
