1 SpecMate Cable Tray Systems Center Spine Cable Tray A/SRA Series S pecmate Center Spine Cable Tray is an easily installed cable support system designed with many unique features to provide safety, reliability and flexibility for future expansion. Removable, replaceable and interchangeable rungs, unique pivot connectors and field modifiable fittings combine to allow installers to easily maneuver around unforeseen obstructions and sudden changes in elevation. In order to reduce installation time, each tray also comes with preassembled couplings. Never before has hanging cable tray been so easy! SpecMate Center Spine Cable Tray can be used to construct a complete cable tray system with controlled 2" [51mm] nominal bend radius that meets the specifications for fiber optic and UTP/STP cabling and exceeds TIA 569 requirements for communications pathways. Designed for use in retrofit, new or existing applications. Specify SpecMate Cable Tray and fittings, available only from Wiremold. Complete System, including Fittings 1" [25mm] wide rungs, unique to Wiremold, provide the widest cable laying surface available. These removable, replaceable and interchangeable rungs allow for easy field modification, future expansion and true cable management. Complete system, including 2" [51mm] Fiber Optic radiused fittings. Install a complete Cable Tray System, through the use of SpecMate Field and Flo-Thru Tees, Crosses, Horizontal and Vertical Pivot s. These fittings provide a 2" [51mm] cable bend radius and exceed the recommendations of TIA/EIA 568-A. WIREMOLD EXCLUSIVE FEATURE! Removable, replaceable and interchangeable rungs provide flexibility. Unique screw-in rungs can be removed and replaced with longer rungs for future expansion or modification without removing the cables, allowing for true cable management. Rungs can also easily be removed in the field to avoid obstacles. WIREMOLD EXCLUSIVE FEATURE! Standard 1" [25mm] wide rungs provide the widest cable laying surface available. Provides support surface for fiber optic and communication cabling which can be damaged by cold flow cable insulation degradation under load. When this is not a concern, 5/8" [16mm] wide SRA Series rungs are available. WIREMOLD EXCLUSIVE FEATURE! Extruded rungs provide direct connection for accessories. 1" [25mm] A Series rungs are extruded with internal screw threads to accept rung mounted accessories like conduit adaptors and cable dropouts. WIREMOLD EXCLUSIVE FEATURE! Preassembled splice connector. A splice connector is provided, preassembled to the tray, to facilitate installation. WIREMOLD EXCLUSIVE FEATURE! Features & Benefits Center lines are provided as drilling guides. All spines and fittings are designed with center alignment marks to make adding screw holes easy in the field. Rungs are factory fitted with protective plastic caps. All rungs are capped to prevent damage to cables and injury to the installer. WIREMOLD EXCLUSIVE FEATURE! Tray, rungs and fittings are available factory painted in a wide variety of colors and textures. Can be used to enhance the aesthetics of any installation or allow for visual differentiation between cable runs. 3" [76mm] center spine serves as a barrier between services. The 3" [76mm] spine serves as a barrier separating one channel of the tray from the other when used with 3" [76mm] rungs. Spine extenders are available for use with 4" and 6" [102mm and 152mm] rungs as well as dividers to provide barriers within each channel. Center Spine Cable Tray: Installs in half the time of conventional ladder tray. Can be loaded from sides of tray in most cases. Uses half the hanging and joining material of conventional ladder tray. Allows for full cable visibility and requires less space for access. Can be hung as close to ceiling as code allows. Custom lengths, widths, heights are easily accommodated. For configurations not shown please consult the factory. ED691R3 Updated August 2005 For latest specs visit

It is not necessary that this fitting radius match the width of the cable tray being used. Rather, the fitting radius must be sized to accommodate the bend radius and stiffness of the cables that will be run in the system and must be equal to or greater than the cable manufacturer s recommended minimum bend radius for the largest cable anticipated to be installed in the cable tray. When several cables are to be installed in the same cable tray run, consider a larger fitting radius to ease cable installation. Consult the cable manufacturer for their recommended minimum bend radius for each individual cable. PLEASE NOTE: The overall physical dimensions of a Cable Tray Fitting increase dramatically as the specified fitting radius of a cable tray fitting increases. This factor, as well as cost, makes the selection of the smallest acceptable fitting radius the most desirable. When larger radius fittings are required, the entire cable tray system layout must be designed to allow adequate space. Please consult the factory for further details. Fitting Radius 10
