Conveyor-head pipe stands use their wide-roller head to position pipe on jobsites or load pipe into threading machines and roll groovers. Pipe glides back and forth along the roller, and the roller head moves up or down to set pipe at a proper working height. These pipe stands also feed bar stock, boards, and long workpieces into table saws, planers, and other machinery. Their base provides a stable footing to resist tipping when standing on a level, flat, solid floor.
