Concealable double acting fastener for wallboard

摘要

A first wallboard and a second wallboard in edge-to-edge abutment are secured to an underlying stud by a double acting fastener which bends around the stud from a flange to the web where a screw passing through a bight in the fastener holds it in place. Oppositely oriented wire talons 20 and 25 are extensions of a first arm 17 and a second arm 18, respectively. Talon 20 is impaled in the edge of the first wallboard and talon 25 is impaled in the edge of the second wallboard. A loop 23 in the second arm 18 rests behind the first wallboard and both arms rest behind the second wallboard. A force tending to move either wallboard away from the stud is resisted by both arms.
