Powered Roller Conveyors | McMaster-Carr
Conveyor extensions expand the length of your set up. Add extensions to each side, but the drive section must remain at the center of the conveyor's length. Extend conveyors with 4 1/2 " roller spacing up to 50 feet long and conveyors with 6" roller spacing up to 70 feet long. Stands adjust in height for a flexible conveyor set up.
