Cable Tray - Introduction and Installation

Introduction

The Wiremaid Products Division of Vutec Corporation introduces Cable-Mgr. cable trays, innovative, cost-effective products that easily adapt to the most difficult installations. The award-winning PRO-10 is designed for the lowvoltage industry and was developed with the architect, engineer and installer in mind. The PRO-10 has pre-fabricated junctions/intersections making it easy to install. The M.E. 2 also comes with factory-fabricated junctions. This product can be cut to custom lengths at the installation site, making it as convenient as it is cost effective.

Features and Benefits of Pro 10

PRO-10 is available in three wire diameter choices – CM10(Ø.120), CM20(Ø.187) and CM30(Ø.250) – to accommodate various cable tray load capacities. No cutting or bending is required on any of these styles. The PRO-10 CM20 cable tray, with a grid pattern of 2” x 4”, is the standard that provides a solution for most cabling applications. CM20 is UL-classified, powdered-coated and available in widths of 6”, 8”, 12”, 18”, or 24”; lengths of 1’, 2’, 5’, 8’ or 10’ and depths of 2”, 4”, or 6”. The PRO-10 CM10 cable tray, with a 2” x 2” grid pattern, is the lightweight solution for fiber optic cabling that minimizes cable sagging or dropping. CM10 cable trays come in widths of 2”, 4”, 6”, 8” or 12”; lengths of 1’, 2’, 5’, 8’, and 10’ with depths of 2” or 4”. A new wire diameter, CM30, is the heaviest weight version of the PRO-10 cable trays, and provides the optimum support for heavy weight cable situations.

Installing PRO-10 Cable Tray

PRO-10 should be installed from the originating head-end i.e., the electrical or telecommunications closet. Once the pathway has been established, it is important the layout of the pre-fabricated junctions be installed first. This allows for field measurements to be taken before installing the cable tray. If the straight sections are installed first, it will cause unnecessary field adjustments. Each section has loops at each end. When the sections are connected, the loop on the bottom aligns under the galvanized masked area of the adjoining section. The loop on the side slides into the outside loop guide. Once the trays are aligned, install the 5/16” carriage bolt (included) through the loops with the threaded end to the
outside of the tray. Install and tighten the flanged nuts with a 1/2” socket. This reduces the chances of damage when pulling the cables. Elevation may be adjusted by using pre-fabricated drop with universal hooks (Fig. 1) or individual straight sections with universal hooks and extenders (Fig. 2). Adjust the length with the PRO-10 cable tray extensions CM-
58 (Fig. 3). The extensions fit into the side guides facilitating adjustment of the tray up to 6 inches on each end. To make horizontal bends, bolt one CM58-5 curved tray extension to each tray side loop. After positing the trays to the desired curvature, tighten securely. It is not recommended that the cable tray be cut as it will interfere with the grounding
characteristics and UL classification.
