For sturdy and reliable scaffolding, the Qual-Craft Pump Jack is a must. This low-cost, foot-operated jack adjusts up to a height of 30 feet and is made of rugged steel with a weather and rust resistant powder coating. Its state of the art design accommodates two 2- x 10-inch wood planks with toe boards attached (poles and planks are sold separately, of course) and it secures those poles into place with a positive double lock system. Painting, building, repair, roofing, and all other forms of maintenance are now easier and safer thanks to this handy pump jack. Measures 22.5L x 25W x 11H inches.
