Vertiv Cable Runway Support Brackets - GL-CR-RSB58

Vertiv GL-CR-RSB58 Cable Runway Support Brackets

Overview

The Vertiv GL-CR-RSB58 is a support bracket kit for Vertiv Vertiv cable runway and cable management systems, designed to anchor and stabilize overhead or wall-routed cable runway runs in structured cabling installations. Where long unsupported runway spans risk deflection under cable load, these brackets provide the intermediate support points that keep runs level, code-compliant, and mechanically sound — a practical necessity in data centers, network closets, and equipment rooms where cable density is high and rework is costly.

GL-CR-RSB58 fits into the broader Vertiv Geist cable runway accessory ecosystem, which includes splice kits, end caps, cable retaining posts, hanger brackets, and junction hardware. Selecting the right support bracket for your specific runway width and mounting surface is the key integration decision.

Compatibility

The GL-CR-RSB58 is designed for use with Vertiv cable runway systems and compatible Vertiv rack enclosures and cable management infrastructure, including:

• VRX-45U-2436-M6: 4-post VRX variable-depth rack, 45 RMU, 24–36″D, 19 or 23″ EIA
• CMR-45U10 / CMRX-45U30: Cable management racks, 45 RMU, standard and premium depth
• UCR-HRS-2U4 / UCR-HRS-4U4 / UCR-HRS-6U4: Universal cable runway hanging racks, 2–6 RMU, 4″D
• GL36WDX / GL24SRD: Vertiv wall-mount and swing-rack enclosures
• GL-CR accessory family: Pairs with GL-CR-VSB (vertical support bracket), GL-CR-TSB6 (triangular support bracket, 6″W), GL-CR-SHBK (slotted hanger bracket kit), GL-CR-BSK (butt splice kit), GL-CR-JSK (junction splice kit), GL-CR-CRP4/CRP8 (cable retaining posts), and GL-CR-VWB (vertical wall bracket kit of 2)

Verify your runway width and mounting surface type before ordering — bracket geometry and hardware attachment points vary across the GL-CR accessory line. Consult Vertiv's technical drawing resources for dimensional confirmation prior to installation.

Installation Notes

Installation hardware and dimensional drawings (DRWG/.DWG/.ZIP formats) are available through Vertiv's racks portal. Revit and STP files are provided for BIM-integrated design workflows. Review the applicable installation instruction PDF for torque specifications and mounting constraints specific to your surface type (wall, ceiling, or rack-top attachment).
