A sheet material lifting and retaining apparatus including a shaft member having a longitudinal axis is described. A gas cylinder assembly is secured to the shaft member, the gas cylinder assembly having an axis of operation that is generally coaxial with the longitudinal axis of the shaft member. A sheet material contact member is secured to the gas cylinder assembly. The shaft member can include a length adjustment mechanism, which may be provided as a telescoping tube arrangement having a plurality of telescoping aluminum tubes. The gas cylinder assembly can include a self-contained gas cylinder. An end fitting can be secured to a first end of the gas cylinder, with a shaft attachment member secured to a second, opposite end of the gas cylinder. An actuator can be provided to selectively control actuation of the gas cylinder. The actuator of the gas cylinder assembly can include a rod portion extending generally parallel to the shaft member. The shaft member can include an attachment bracket adapted to be secured to the shaft attachment member of the gas cylinder assembly. The end fitting can be adapted to be secured to the sheet material contact member, which may be provided as a generally planar nylon block. A floor contact member, which may include a cushion contact surface, can secured to an end of the shaft member opposite the gas cylinder assembly.
