Damaged?: Unknown With the Steelman 11.5 inch wide adjustable single roller material support stand, you'll always be a smooth operator on the job. It's ideal when guidance and control are needed to support and keep long materials, such as wood or pipes, steady and level. It prevents cut material from falling and possibly swinging or bouncing back into the path of spinning blades. The height is fully adjustable thanks to an easy lock lever with a minimum height of 28 inches and a maximum of 44 inches and can be quickly folded up flat for compact storage and transport.
