ABSTRACT:
An elongated channel-shaped body is provided including a pair of opposite side longitudinal flanges and an elongated bight portion extending between and interconnecting one pair of corresponding longitudinal edge portions of the flanges. One of the flanges is rigid with and thus fixed relative to the bight portion and the other flange is pivotaly supported therefrom for oscillation about an axis extending longitudinally of the body along the adjacent marginal edges of the pivoted flange and the bight portion. The pivoted flange is oscillatable between a closed position with the adjacent sides of the flanges substantially parallel and an open position with the free longitudinal edge of the pivoted flange swung away from the free edge of the rigid flange. An elongated lever has one end pivotaly supported from one end of the bight portion on the side thereof remote from the flanges and an intermediate portion of the lever includes portions engageable with remote side surfaces of the longitudinal midportions of the flanges to cam the pivoted flange toward its closed position and to brace the rigid flange against flexure away from the pivoted flange. One end of the bight portion includes a structure defining a transversely extending and endwise outwardly opening channel for cradling a piece of lumber in the channel and the other end of the bight portion includes a transverse outwardly projecting abutment flange which may be utilized to support a wall board relative to a stud with which the clamp is clampingly engaged.
