The Light Source 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. Tighten the bolts to 11 foot pounds, which is about as tight as as can be done with a 6" hex key wrench.
