Abstract:
A harnessing device formed by a locking head and an attached serrated strap with gripper rails. The head contains a guide channel for receiving the strap after encirclement of the items to be harnessed, and an internal locking tang. The serrated strap has side rails which are proportioned to grip the encircled items. The desired gripping action is facilitated by the inclusion of serrations on the rails.
A harnessing device formed by a locking head and an attached ladder strap. The head contains a locking tang and a guide channel that receives the strap after encirclement of items to be harnessed. The tang engages the rungs of the ladder strap for the adjustable retention of the harnessed items. The free end of the strap has a light-weight webbed tail that facilitates the insertion of the strap into the head. The strap is advantageously molded of a stretch reorientable material and is subsequently stretched to produce a suitable strengthening and elongation of the webbed tail.
