Abstract: A traction rack for a rear axle driven truck is provided which comprises a generally rectangularly-shaped assembly having side elements sized for placement on the bed of the truck between the wheel wells, lead weights attached to respective ends of the side elements to form the rectangular assembly having substantial weight concentrated near the ends of the assembly near the wheel wells, one of the side elements having an extension on each end exceeding the spacing between the wheel wells to facilitate placement and restraint of the rack over the rear axle.

Abstract: A method of holding flexible sheet or strip material utilizes a holding device comprising a loop holder recessed internally to provide a polygonal passage for the reception of a loop-expanding element. A second, relatively shallow passage in the loop holder extends from and along the length of the polygonal passage to the outside of the loop holder for accommodating emergent portions of a received loop portion of flexible sheet or strip material to be held. The loop-expanding element is polygonal in configuration and of size adapted to be non-rotatively accommodated by the polygonal passage and is adapted for positioning within the loop portion of the flexible sheet or strip material to be held that is positioned within the polygonal passage.
