Abstract
Sheet material lifts including an elongate body extending along a longitudinal axis between a first end and a second end, a foot extending transverse the longitudinal axis from the second end of the elongate body, a support element disposed on the foot distal the elongate body, a base defining a fulcrum coupled to the foot, and an arm extending transverse the longitudinal axis from the elongate body at a position intermediate the first end and the second end. In some examples, the arm includes a sleeve, and a shaft slidingly mounted within the sleeve, the shaft being configured to slide along a path between a retracted position proximate the elongate body and an extended position distal the elongate body.
