Panduit CMVDR1S Open-Access Vertical Cable Management D-Ring

The Panduit CMVDR1S is a 1RU vertical cable management D-ring engineered for standard EIA communications racks. Its defining feature is the flexible Open-Access arm design that eliminates the need to thread individual cables through fixed rings—installers can load complete cable bundles in a single motion, then close the arm to secure routing. This addresses a persistent pain point in high-density rack builds where traditional closed D-rings force time-consuming per-cable threading. Measuring 2.38" high by 2.05" wide, the CMVDR1S occupies minimal rack real estate while providing robust strain relief and cable pathway management for network, security, and AV infrastructure.

Key Features

Open-Access flexible arm allows full cable bundle installation without threading individual conductors

1 RU vertical mounting footprint fits standard 19" EIA racks and cabinets

Black powder-coated finish matches professional rack infrastructure

2.38" height × 2.05" width (60.32mm × 52mm) dimensions accommodate bundled cables up to approximately 1.5" diameter

RoHS-compliant construction meets environmental and disposal regulations

10-pack carton quantity (individual unit packaging) optimizes inventory for multi-rack deployments

The Open-Access design philosophy directly addresses installer efficiency. Traditional closed D-rings require you to estimate cable count during initial installation, then thread each addition through the ring opening—a workflow that breaks down in iterative deployments where circuits are added over months or years. The CMVDR1S flexible arm opens to accept pre-bundled cables (cat6, fiber trunk, coax, power, etc.), then secures them with a passive retention mechanism. This becomes critical in security integrator workflows where camera home-runs, access control risers, and intercom circuits are often pulled in separate phases. The 1RU vertical orientation works well at the top or bottom of equipment zones, providing a 90-degree turn radius for cables exiting switches, NVRs, or patch panels before they route to vertical cable managers or exit the rack.

The 2.05" width accommodates typical bundle diameters found in 12-48 port switch deployments. For reference, a bundle of twelve cat6 cables (0.23" OD each) arranged in a loose circular cross-section measures approximately 1.2-1.4" diameter—well within the CMVDR1S capacity. The black finish integrates with standard relay rack aesthetics in server rooms, IDF closets, and equipment headends. Mounting hardware accepts standard rack screws (typically 10-32 or 12-24 depending on rack threading). The unit ships individually packaged within 10-piece cartons, making it straightforward to order exact quantities for projects ranging from single-rack IT closets to multi-building campus rollouts.

Panduit's CMVDR1S meets RoHS environmental compliance standards, ensuring it qualifies for installations subject to EU directives or corporate sustainability policies. The vertical D-ring form factor is a proven cable management topology—its curved profile prevents kinking at bend transitions, maintains minimum bend radius requirements for category-rated copper and single-mode fiber, and provides strain relief that reduces weight load on rear panel connectors. For commercial integrators managing TIA-568 or TIA-606 labeled infrastructure, the open-access workflow means cable identification and bundle documentation remain visible throughout the installation process rather than being obscured during threading. This is a purpose-built component for racks where cable density, future expansion, and installation speed are equal priorities.
