With a welded, tubular, steel construction, the JET Folding Adjustable Roller Stand provides a rugged work support that's both lightweight and durable for enhanced productivity. The 12-1/2-inch wide, smooth-action roller facilitates improved handling of heavy unwieldy materials. The telescoping post on the adjustable roller stand allows adjustment of heights ranging from 25-1/2 to 42 inches for maximum flexibility. The height post features a knurled surface for more secure connections with the locking knob system. Furthermore, a four-point contact with non-marking feet ensures superior stability when under load. When you are done using the stand, just fold in the support leg to minimize its storage space.
