Abstract
A metal frame system for use as a door frame, window frame and the like utilizing vertical frame members adapted for attachment to wood or steel studs, employs unique wedge member sets comprising pairs of complementary shaped wedges. Each of wedge members has two wedges of generally congruent shape but having inverted interface surfaces, one such interface surface abutting the other in compressive contiguous relation whereby to fill the space between the vertical member and the underlying wood stud. Linear movement of one wedge relative to the other provides an expedient adjustment capability for fitting the frame system into the study assembly. Rotation of one wedge relative to the other provides a convenient way of compensating for irregular wood or steel stud surfaces that might otherwise prevent proper orientation of the forms relation to the studs.
