Panduit NCMH2 NetManager Horizontal Dual-Sided Cable Manager
Overview
The Panduit NCMH2 is a 2RU horizontal dual-sided cable manager from the NetManager™ line, purpose-built to organize and protect copper and fiber cabling in any standard EIA 19-inch (483mm) rack or cabinet. At 9.7 inches deep and 19 inches wide, it occupies exactly 2U of rack space and handles both front and rear cable paths in a single unit — eliminating the need for separate front and rear managers in most installations. The black ABS plastic construction includes a removable hinged cover that lets you route and re-route cables without disassembling the manager, which matters when you're making moves, adds, or changes in a live rack.
Key Features
- Dual-Sided Design: Routes cables on both front and rear faces simultaneously — one NCMH2 replaces two single-sided managers, reducing rack unit consumption and simplifying cable administration in high-density installations.
- Bend Radius Control: Built-in radius guides prevent copper and fiber cables from being kinked or pinched. Proper bend radius is especially critical for fiber, where tight bends increase insertion loss and can cause intermittent link faults that are notoriously difficult to troubleshoot.
- Removable Hinged Cover: The cover snaps off without tools for unobstructed access during patching or re-routing, then snaps back to protect cables from accidental pulls and snagging on adjacent equipment.
- Standard 19-Inch EIA Rack Compatibility: Mounts in any 19-inch (483mm) standard rack or cabinet — open-frame, enclosed, two-post, or four-post. No proprietary hardware required.
- 2RU Form Factor (88.1mm height): Two rack units is the standard allocation for a horizontal manager paired with a 1U patch panel. The NCMH2 fits that pairing without wasting rack space.
- ABS Plastic Construction: Lightweight and impact-resistant. Appropriate for structured cabling environments where metal managers would add unnecessary weight to already-loaded racks.
- RoHS, UL 2416, and CSA C22.2 Compliance: UL 2416 is the specific UL standard for wire and cable management systems — relevant for inspected data center and commercial building deployments where listed components are required. RoHS compliance covers EU hazardous substance restrictions, and CSA C22.2 covers Canadian electrical code requirements.
Integration and Compatibility
The NCMH2 is designed for standard EIA 19-inch racks and cabinets — the same form factor used by virtually all commercial networking, security, and AV equipment. It pairs directly with Panduit patch panels, switches, and fiber enclosures in the same rack. If you're building out a structured cabling installation alongside network switches or NVR appliances, plan one NCMH2 per patch panel row. For cable management planning in larger deployments, see the cable management planning guide. The competitor cross-reference for this unit is WMB2H.
Frequently Asked Questions
Q: What rack size does the NCMH2 fit?
A: The NCMH2 mounts in any standard EIA 19-inch (483mm) rack or cabinet — open-frame, two-post, or four-post enclosed. It does not require a proprietary rack.
Q: How many rack units does the NCMH2 occupy?
A: It occupies 2 rack units (2RU), with an overall height of 3.47 inches (88.1mm).
Q: Is the NCMH2 suitable for fiber cabling?
A: Yes. The bend radius control built into the manager is designed to protect both copper and fiber network cabling, preventing the tight bends that cause insertion loss and signal degradation in fiber runs.
Q: Does the NCMH2 meet UL listing requirements?
A: The NCMH2 meets UL 2416 (wire and cable management systems), CSA C22.2, and is RoHS compliant — satisfying common inspection and compliance requirements for commercial and data center installations.
Q: What is the depth of the NCMH2?
A: The NCMH2 has a depth of 9.7 inches, which accommodates typical horizontal cable runs without protruding excessively into the rack aisle.
The NCMH2 earns its place in structured cabling installs specifically because of the dual-sided design — at 9.7 inches deep, it handles both the front patch and the rear horizontal run in a single 2RU slot, which in a fully loaded 42U cabinet is the difference between a clean, maintainable rack and a cable tangle that nobody wants to touch six months post-install.
Technical Highlights:
- Dual-Sided Manager, 2RU: One unit manages front and rear cable paths — consolidates two single-sided managers into one slot, freeing rack space for active equipment without sacrificing cable organization.
- UL 2416 / CSA C22.2 Listed: These listings satisfy the AHJ inspection requirements common in commercial construction and enterprise data center buildouts — you won't be pulling the manager out post-inspection to swap in a listed component.
- Removable Hinged ABS Cover: Tool-free removal means MACs (moves, adds, changes) don't require partial rack disassembly — critical in environments where the rack stays live during re-patching.
Deployment Considerations:
- Plan one NCMH2 per patch panel row — the 2RU height is sized to pair with a standard 1U panel, with the manager sitting immediately above or below in the same rack section.
- The 9.7-inch depth accommodates most horizontal runs, but verify against your cabinet's usable depth if you're working with shallow-depth wall-mount enclosures — some compact cabinets run tight on rear clearance.
The NCMH2 is the right call for enterprise network closets and security head-end racks where patch density is high, fiber is in the mix, and the installation needs to pass inspection — not for lightweight or temporary deployments where cable management is an afterthought.
