Abstract: A low profile fixture clamp which provides a clamping force in two perpendicular directions through the motion of a pneumatic cylinder in a single plane. The principle component of the clamping force is a horizontal force in-line with the force generated by the pneumatic air cylinder. An additionally vertical downward clamping force is also generated.

Abstract: A truss element positioning clamp for use on a truss fabrication table to position a truss element in a preselected position comprising a clamp chassis slideably disposed over a clamping channel formed in the surface of the truss fabrication table including a truss stop operatively disposed on the upper surface of the clamp chassis to selectively engage and position the truss element of a truss having at least one guide member formed on the clamp chassis and disposed within the clamping channel to prevent rotation of the truss element positioning clamp relative to the clamping channel and a clamp stop movably coupled to the clamp chassis extending into the interior of the clamping channel and selectively movable between a first position and a second position such that when the clamp stop is in the first position the clamp stop is disengaged from the inner surface of the clamping channel whereby the truss element positioning clamp may be positioned longitudinally along the length of the clamping channel and wh
