The pinchweld clamp is not a continuous clamp – the jaws cover an area of 200 mm
with a 75 mm cutout in the center. This cutout allows the clamp to fit around
obstructions such as fender bolts, flanges, etc. The two smaller jaws allow for a greater
biting force than a single large jaw. The clamp is constructed from a special high
strength ferriferous steel allowing it to be made light in weight without losing strength.
The four pinchweld clamps are held in a rigid anchoring framework with the four steel
anchoring bars and wedges which secure the clamps to these bars. The clamp bodies
have wide mounting flanges and are cast in a precision mold to keep the clamps
square to the anchoring bar frame.
