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. Junctions/intersections lengths are standard: 12 inches wide or less come 2 feet in length and junctions/intersections more than 12 inches wide come 3 feet in length. 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 inch carriage bolt (included) through the loops with the treaded end to the outside of the tray. Install and tighten the flanged nuts with a ½ inch 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. It is not recommended that the cable tray be cut as it will interfere with the grounding characteristics and UL classification.
Cable Tray Elevation Change CM15, CM25 and CM35 Drop
During some installations, it may be necessary to make an elevation change under or over an obstruction. This is accomplished by using a Drop. The Drop connects to a section with universal loops acting as a hinge. Set the desired angle, insert bolts, and tighten the hex flanged nuts. Powder-coating should be removed to ensure ground continuity.
Cable Tray Elevation Change Using Straight Sections using Universal Loop (CM-70) and Universal Loop Off-Set (CM-71)
Straight sections can be used to make elevation adjustments. The universal loop CM-70 is attached in the same way as a Drop. Scrape the powder-coated area where the loop attaches to ensure continuity in grounding. Bolt the universal off-set to the masked area on the side rail and to the loop attached to the next section. Place a 5/16 bolt through the loop to provide a pivot point. To set and lock the angle of elevation, use a 5/16 flanged nut.
Cable Tray Extension using Offset Loop (CM-58)
During some installations, there may be sections that do not meet. The offset loop was designed for this. It is critical that the cross-sectional diameter of the offset loop and the cable tray or junctions be the same diameter to insure proper contact surface alignment. The off-set loops bolt to the existing loops on the tray. When attached to each end of a section, a lateral adjustment of up to 12 inch is possible. To adjust, slide the cable trays, junctions or offset loops to meet and then tighten the flange hex nuts. This same method is used to lengthen the cable tray drops if needed.

Wire Management Products
The Wiremaid U.S.A. Products Division of Vutec Corporation entered the cable tray arena with the development of PRO-10 and M.E.2 wire cable tray systems.
PRO-10 cable tray is an innovative and cost-effective system that easily adapts to the most difficult installations. Designed for the low voltage industry and developed with the architect, engineer and installer in mind, PRO-10's pre-fabricated junctions/intersections and ease of installation make it a cost-effective choice of contractors throughout the United States.
M.E.2 cable tray management system is manufactured with rigid .187 diameter zinc-plated steel wire, welded in a two inch by four inch grid facilitating easy cable break outs while supporting the cable. The open grid design prevents dirt build-up and dust experienced in closed cable trays.
