Fastener for strut channel

摘要

A self-contained fastener is provided for attaching to a structure having opposing edges that flank a cavity across a gap. The fastener includes a grip member, a clamp member and a latch member. The grip member has a knob and an inner annulus disposed thereon along an axis of symmetry. The knob has a central through-hole coaxial with the inner annulus. The inner annulus has an arc tab that radially protrudes therefrom. The clamp member includes a boss and an outer annulus disposed thereon. The boss has first and second dimensions perpendicular to the axis, the first dimension being shorter than the gap. The clamp member is flanked by opposing ledges along the second dimension. Each ledge is arranged to engage a respective edge of the structure. The inner annulus is coaxially insertable into the outer annulus. The latch member includes a stud and a flange. The stud is insertable at a proximal end into the inner annulus and the through-hole. The flange is disposed at a distal end of the stud and has a third dimension shorter than the gap. The flange and the block can be inserted into the cavity along the respective third and first dimensions through the gap. In response to clockwise turning, the knob rotates the tab within the angular notch until inhibited by the outer annulus, whereby the proximal end of the stud retracts into the through-hole, thereby engaging the fastener to the structure.
