ABSTRACT:
A post member supports a stationary lower jaw and a movable upper jaw. Two openings in the upper jaw are spaced one above the other the same distance apart as a plurality of equispaced openings on the post member. A pair of pins are insertable into the openings in the upper jaw and openings in the post member to secure the upper jaw in position on the post member. With a pin in place in the upper opening in the upper jaw and a pin removed from the lower opening in the upper jaw that jaw can be tilted upwardly about the pin in the upper opening to facilitate installation of the post member and jaws on a beam.
