Thomas & Betts' Kindorf® Trapnut(TM) Strut Fastener Speeds Installation of Trapeze Supports
Fewer Parts Result in 30 to 43 Percent Less Time to Install
MEMPHIS, Tenn. - Nov. 16, 2006 - Thomas & Betts' Kindorf® Trapnut(TM) Strut Fastener reduces the time to install trapeze framing and support systems by eliminating the need to thread a nut from either end of a threaded rod. Time studies indicate that the Trapnut Strut Fastener takes 30 percent less time to install in new-work applications than standard fasteners, and 43 percent less time in retrofit applications.
The Trapnut Strut Fastener features a scissor design, which consists of top and bottom plates fastened with a pin, enabling the plates to swivel open and close, similar to a clamp or pair of scissors. Closing at any position on the threaded rod, the scissor design and precision threads allow for fine-tuned adjustment in either direction. The Trapnut Strut Fastener also features precision threads that hold the threaded rod in position, while removable and reusable locking pins secure the threaded rod in place.
The Trapnut Strut Fastener can be installed between the existing trapeze and the beam clamp, eliminating the need to disassemble an existing trapeze to run additional conduit above it in retrofit applications. The reduction of installation time is especially significant when the ends of the threaded rod are not accessible.
The Trapnut(TM) Strut Fastener's combined function as a hex nut, square washer and flat washer means fewer parts for installation. Its sturdy steel construction is load bearing, and will deliver load support comparable to the threaded rod on which it is installed.
"We conducted a time study in which two contractors installed 15 feet of two-inch Thinwall Conduit, supported by typical trapeze assemblies," said Mark Pfaller, product manager for Thomas & Betts. "We compared the installation time using standard washers and nuts with using the Trapnut(TM) Strut Fastener in both a new-work and a retrofit application. The Trapnut Strut Fastener took 30 percent less time in the new-work application and 43 percent less time in the retrofit application."
To install, hold the Trapnut Strut Fastener in the open position, insert the bottom plate on the rod and close the top plate. Press the locking pin with pliers, then use pliers to tighten the Trapnut to the desired position.
