The Qual-Craft Steel Pump Jack System Kit is a super portable, go-anywhere wood staging system for all roofing and siding jobs. It's like having your own efficient, economical do-it-yourself scaffolding kit. Two pump jacks fit on fabricated poles made of spliced 2 x 4s (not included) and accommodate a platform comprised of two 2 x 10 wooden planks measuring up to 6 feet long with toe boards attached (not included). A positive double-lock system brake allows each jack to secure itself to the wood poles. Once assembled, just pump the patented steel pump jacks with your foot to raise the platform, or crank with your hand to lower the platform to a desired height. U.S.A.
