Mega-Gridlock Variant

Product Overview

The Mega-Gridlock is designed for permanent pipe grid installations in studios and theaters. It joins 2 overlapping pipes together in a 90 degree joint. Grooves act as a wrench, keeping the nut from turning during installation. The Mega-Gridlock can be installed with a hex key tool in a battery drill.

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)

The Mega-Gridlock can be used on curved track down to a radius of 3 feet, or on a circle with a diameter as small as 6 feet.

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