Mega-Gridlock

The Mega-Gridlock is designed for permanent installations in studios and theaters. It joins 2 overlapping pipes together in a 90 degree joint. The side grooves act as a wrench, keeping the nut from turning during installation. Fastens any combination of 1-1/2" pipe (1.9" OD), 1-1/4" pipe (1.66" OD), and 2" OD Tube. (Tight fit on 2" OD tube) Tighten the bolts to 11 foot pounds, which is about as tight as as can be done with a 6" hex key wrench.
