Working with large and heavy sheet goods can be difficult. Our Heavy-Duty Rollerball guides make this, and other shop material handling tasks easier. Unlike traditional support rollers, these guides swivel in all directions making it a snap to position and feed large workpieces to get perfect results. This 6-Piece set can be added to infeed and outfeed tables, work stands, and anywhere you may need to maneuver large workpieces. Measuring 7/8” tall with a 2" wide base, the 5/8” diameter hardened steel ball bearing can support up to 55 lb. each with the 6-piece set together supporting over 300 pounds! Mounting hardware included.
