Abstract: A bolt receiving clamp for use with a Traffic box having a claw plate with a first and second claw welded to a bottom tube for capturing a lowest edge of a corner of a traffic box. A top plate, welded to a top tube, the top plate gripping an inner flange of the box above the claws. The top tube is inserted in the bottom tube with an insert and bolt for adjusting the separation between the claws and the top plate. A strut channel nut plate sub-assembly is welded to the top plate. A safety bolt, for holding a cover on the box, passes through a channel in the top plate into the strut channel nut plate sub-assembly, to engage and thread into a strut channel safety nut, that is spring loaded and slides on rails to capture the safety bolt.

Abstract: A quick-release fire hose clamp for securing a fire hose in place on a fire-fighter's shoulder includes a strap attachment assembly which is releasably fastenable to a backpack strap disposed over the fire-fighter's shoulder. The clamp includes a clamp mechanism that extends upwardly from the strap attachment assembly and has a semi-cylindrically shaped lower hose support body, and a confronting semi-cylindrically shaped upper clamp shell that is pivotable upwardly to enable a length of hose to be laid on the lower hose support body, pivotable downwardly to exert a compressive clamping force on the hose, and pivotable upwardly to release the hose. The clamp mechanism includes a pivotable clasp lever that has a cammed lower surface for exerting a compressive force on the upper surface of the upper clamp shell, the clasp lever being threadingly movable up and down to accommodate larger and smaller hoses, respectively.
