The unique scissor action of the Trapnut Strut Fastener closes at any desired position on the threaded rod. Once closed, precision threads trap the threaded rod for a sturdy hold that can be adjusted up or down for fine-tune positioning. While the versatile Trapnut has a locking pin that holds it in the desired position, it can also be removed and reused. Unlike a Hex Nut, there is no need to thread the Trapnut from either end of the rod, saving valuable time on the job. While the Trapnut Strut Fastener is a time-saver for new construction, it is invaluable for retro-fit applications. Rather than disassembling an existing trapeze to run additional conduit above it, Trapnut can be clamped between the existing trapeze and the beam clamp for a speedy retro-fit solution. It's ideal for applications where the rod ends are not accessible. Trapnut has a sturdy steel construction that is load bearing, so you can be confident of a solid installation. And, Trapnut functions as a Hex Nut, square washer and flat washer combined, so there are fewer parts to keep up with on the job.
