Mobile steel heavy duty 20" x 20" platform. You can mount a 1.5" to 2 3/8"diameter pipe. This is a platform to mount a vertical pipe for the The Silent Paint Remover™ articulating arm on to. Use a 2.38" diameter galvanized fence post for great stability and a much better platform compared to a stand with legs that you could trip over. Easily add weight to the surface of the base if necessary. Mobile base weight 26Lb. Includes 4 thermoplastic rubber wheels for easy mobility. For stationary applications, remove the wheels and bolt the base to two 22" long 2 x 4 studs creating a sled.
