Abstract: A strap tie down device combining the winch-pulley effect comprising an elongated rigid frame made up of a base and two spaced parallel side plates attached perpendicular to opposite sides of said base, at both ends of the frame a set of at least two transverse extending connecting rods joined to both sides of the plate members, the connecting rods being separated from each other by sufficient distance to permit a looping of the strap between the rods, the loops are capable of being held in placed by adding a removable rod under the loop, and a winch-type strap tightening apparatus attached to the side plate members between the inner connecting rods at both ends of the frame, and a device for rotating the winch-type strap tightening apparatus so as to tighten any strap placed in the strap adjusting device, and a device for holding the tightening apparatus to prevent unwinding.
