Abstract: A plastics and metal fencing system includes a cylindrical metal post for engaging into the ground with a square tubular cladding post formed of an extruded plastics material engaged onto the metal post. A fence panel is formed by a top rail, a bottom rail and a plurality of pickets where each of the rails includes a cladding channel of extruded plastics material and a metal reinforcement channel. Each of the rails has the metal channel attached by a metal bracket to the metal post by a screw fastener which passes through the cladding post to engage the metal post such that the rail is rigidly connected to the metal post through the plastics cladding.

Abstract: On a conventional pipe wrench, an L-shaped lever arm has the short bisected arm segment cooperatively disposed over and secured by a fixed pivot to a linear extention of the threaded section of the adjustable pipe jaw. A free pivot disposed at the terminus of the bisected arm secures a roller between and in the short bisected arm segment. The L-shaped lever arm and pivoted roller are adaptively sized and shaped to provide a lock means for the pipe jaw when the lever handle is pressed down against the pipe wrench handle, locking the roller against the wrench handle by compressing the roller in detent against the wrench handle.
