Redesigned ladder-style cable tray
Legrand’s all-aluminum Itray includes a side-rail design that allows midspan splicing and other improved functionality.
Legrand recently introduced a redesigned all-aluminum ladder-style cable tray that the company says “offers enhanced functionality, faster installation and easier ordering.” Called Itray, the product featured side rails designed to allow midspan splicing while maintaining full NEMA load class, Legrand explains. “The tray is lighter and stronger than its conventional equivalents, and minimizes total tray width for tight spaces,” the company adds.
Part of the PW product line, the redesigned Itray was brought to market after study into how to simplify the product line. Bob Crain, director of marketing and product development with Legrand, recalled, “Once we decided to start from scratch on the design, many new features became possible.”
The sidewall, Legrand explains, is designed with structural offsets and a matching splice that makes midspan splices possible, thereby reducing the number of supports and the amount of attachment hardware needed. The tray’s aluminum I-beam design “minimizes total tray width and creates a smooth transition between straight sections and fittings,” the company points out.
Splices snap-in-place and remain in place without the need for bolts, Legrand says, adding that studies showed Itray can be installed up to 30 percent faster than standard tray. Crain added, “We feel this design will significantly reduce installation time and move the contractor off the jobsite much sooner.”
The tray bottoms now feature an I-beam rung design to reduce twist and deflection under load, with heavier gauges for wider widths, Legrand says.
The Itray products will be available in summer 2013, in 4- to 7-inch tray depths and 6- to 36-inch widths. Several bottom and cover designs are also available. The reference to easier ordering comes from the fact that this new design reduces the number of SKUs needed, thereby speeding up shipping times.
