Abstract: A Locking/Tightening mechanism to secure Extension and Step Style Ladders to any general-purpose overhead ladder rack for transportation. The apparatus creates an enclosed system by contouring to the ladder rail or steps and provides a one-way mating Terminal Buckler at the end of its enclosed Belt thereby locking the Ladders securely to the Ladder Rack cross rails.

Abstract: A concrete float body whose bottom (working) surface has a 3D shape/profile/contour over a nose region and a tail region of the float body. The nose region may be tapered across a width dimension of the float body. The tail region may be tapered across a width dimension of the float body. The nose and tail regions may have rounded corners. A perimetal edge of the float body may have a radius. The 3D surface may be produced by extruding, cutting from a solid material, die cast molding, or injection molding the float body wherein the bottom surface has a curvilinear shape along the width dimension, and monotonically decreasing a thickness dimension of the float body between the bottom surface and a top surface by removing material from the bottom surface.
