Panduit WMPH2E PatchLink Horizontal Dual-Sided Cable Manager 2RU
The Panduit WMPH2E is a 2RU horizontal cable manager from the PatchLink™ family, built for 19-inch EIA-standard racks and cabinets where patch cord chaos is an ongoing operational problem. At 19 inches wide, 3.5 inches tall (2RU), and 8.9 inches deep, it gives you front-and-rear cable routing in a single unit — eliminating the need to stack a front-only manager and a rear trough when your cabling runs both directions. If your patch bays have historically been a tangle of slack cord and last-minute zip ties, this is the product class to evaluate.
Key Features
- Dual-sided front and rear routing: A single WMPH2E handles cable egress in both directions — forward to patch panels and rearward toward backbone runs or switches — without occupying an additional rack unit for a second unit. In a dense 48U cabinet, recovering a rack unit matters.
- Dual-hinging front and rear covers: The covers swing open independently on either side, so a technician can access the front cable bundle without disturbing the rear routing path. This pays off during MACs (moves, adds, changes), where blind access to a cramped rear bundle is the usual source of accidentally yanked cables.
- Flexible organizing fingers: The fingers separate individual patch cords into discrete lanes, making it possible to trace and reroute a single cable without disturbing adjacent circuits. In a 48-port environment, that capability directly reduces mean-time-to-restore on physical-layer incidents.
- Closed-pathway design: Unlike open-finger-only managers, the enclosed channels protect patch cords from being snagged during unrelated rack work above or below the cable manager. This matters in colocation environments or shared rack bays where multiple parties work in proximity.
- Bend radius clips included: The included bend radius clips enforce minimum bend radius on patch cords exiting the manager, which is particularly relevant for fiber optic cables where overbending causes measurable signal loss. This is not a courtesy feature — fiber routing without radius control is a support call waiting to happen.
- Supports copper, fiber optic, and coaxial cable: One manager handles the full range of structured cabling media types. You are not buying a fiber-specific unit and a separate copper manager for a mixed-media patch bay.
- Standard 19-inch EIA rack compatibility: At exactly 483mm (19 inches) wide, the WMPH2E mounts in any compliant EIA 310 rack or enclosure — open-frame racks, enclosed cabinets, two-post relay racks — without adapter hardware.
- RoHS compliant: Materials meet RoHS restrictions on hazardous substances, relevant for deployments in the EU or for enterprise procurement policies that require RoHS documentation across all rack infrastructure.
- UL 2416 and CSA C22.2 listed: Both listings confirm the product meets recognized safety standards for wire management devices in the US and Canada — relevant for any installation where the AHJ (authority having jurisdiction) requires listed wire management hardware.
- Black finish: Matches standard black rack infrastructure; no finish-matching order needed in most deployments.
Integration and Compatibility
The WMPH2E installs in any 19-inch EIA-compliant rack or enclosure, open or closed, two-post or four-post. It sits between patch panels and active switching equipment in the horizontal cable management layer of a structured cabling system. The 8.9-inch depth accommodates the slack loop and routing radius required for standard patch cords running to equipment mounted at the front or rear of a four-post cabinet.
In practice, the WMPH2E pairs naturally with 1RU or 2RU patch panels mounted immediately above or below it. A common layout is: patch panel → cable manager (WMPH2E) → patch panel → cable manager, alternating through the panel zone of the cabinet. The dual-sided design means rear cable runs (toward a network switch in the same cabinet) can be routed and maintained independently of the front patch cord field.
Competitor cross-reference: the WMPH2E is a functional equivalent to the Leviton 492RU-HFR and the Ortronics EHWM2 for installations where those models have been specified but Panduit is the preferred infrastructure brand.

Frequently Asked Questions
Q: What rack size does the WMPH2E fit?
A: The WMPH2E is designed for standard 19-inch (483mm) EIA 310 racks and cabinets. It occupies 2 rack units (3.5 inches / 88.9mm) of vertical space.
Q: Does the WMPH2E manage fiber optic cables as well as copper?
A: Yes. According to Panduit's product documentation, the WMPH2E manages copper, fiber optic, and coaxial cables. The included bend radius clips are particularly important for fiber routing to prevent signal loss from overbending.
Q: How deep is the WMPH2E cable manager?
A: The WMPH2E has an overall depth of 8.9 inches, providing sufficient space for patch cord slack storage and proper bend radius management on standard four-post rack installations.
Q: Is the WMPH2E RoHS compliant?
A: Yes. The WMPH2E meets RoHS requirements. It is also listed to UL 2416 and CSA C22.2 standards for wire management devices.
Q: What is the difference between the front-only and dual-sided cable manager versions?
A: The WMPH2E is a dual-sided manager with independently hinged front and rear covers, allowing cable routing and access on both sides of the rack. A front-only manager provides a single cable pathway toward the front of the cabinet only — appropriate when all patch cord runs are front-facing and no rear routing path is needed.
Q: Does the WMPH2E ship with mounting hardware?
A: Panduit's documentation confirms the unit ships with bend radius clips. For specific mounting hardware details, verify with the distributor at time of order, as rack-mount hardware is typically included with standard horizontal cable managers in this product family.
The WMPH2E is the unit I reach for when a rack build calls for bidirectional patch cord management and there is no tolerance for a cluttered rear field. The 8.9-inch depth on this manager is the spec that separates it from shallower units — it gives you enough real estate to execute a proper slack loop on standard 7-foot patch cords without stuffing them into the trough. I have seen shallow managers create more problems than they solve when techs try to force excess cord into an undersized channel.
Technical Highlights:
- 2RU dual-sided form factor: Front and rear cable routing consolidated into 3.5 inches of rack space — one unit instead of two separate front and rear managers, which matters when the patch panel zone is already tight.
- Independently hinged covers: Front and rear covers operate independently, so accessing a rear run does not expose or disturb the front patch cord field. This is the detail that makes MACs faster in a production environment.
- UL 2416 / CSA C22.2 listed: Both US and Canadian safety listings are on the WMPH2E — relevant for any project where the electrical inspector reviews wire management hardware, which is more common on commercial construction than people expect.
Deployment Considerations:
- The 8.9-inch depth assumes a four-post cabinet with sufficient front-to-rear clearance. Verify your cabinet's usable depth before ordering — two-post relay racks with shallow depth or wall-mount enclosures under 12 inches deep may not give the rear cover room to hinge open fully.
- The bend radius clips are included but their count is not specified in Panduit's documentation — confirm clip quantity covers your fiber port count before the installation day, particularly on high-density fiber patch panels where every egress point needs a clip.
This unit is the right call for structured cabling builds in enterprise MDF/IDF rooms, colocation deployments, and data center row cabinets where the rear of the patch panel zone connects directly to switching equipment in the same cabinet and both cable fields need to be maintainable independently over a multi-year service life.
