Mega Grid lock
The Mega-Gridlock is intended for a permanent installation in theatres and studios. It creates a 90 degree connection between two pipes that are overlapping. As a wrench, the side grooves prevent the nut from twisting during installation.
Any combination of 1-1/2" pipes (1.9" OD), 1-1/4" pipes (1.66" OD), and 2" OD Tubes can be fastened (tight fit on 2" OD tube).
