Panduit FQCRCM QuickNet Cassette Rear Cable Manager
Overview
The Panduit FQCRCM is a 1U rear cable manager from the Panduit QuickNet fiber infrastructure line, designed to mount at the back of any standard EIA 19-inch telecommunications rack. Its core job is straightforward but consequential: eliminate the need for separate horizontal cable managers at the rear of the rack while simultaneously storing up to one meter of cable slack per port run — giving installers real slack management and bend-radius protection in a single 1U footprint. If your rack rows are tight and you're tired of unsupported fiber drooping off the back of patch panels, this is the fitting that solves it without adding a separate 1U cable management unit for every cassette shelf.
The FQCRCM mounts directly to the rear rails of a 19-inch rack — no floor space consumed, no additional mounting hardware beyond what attaches to the rack itself. The design targets fiber-optic cassette systems specifically, integrating with fiber optic cable management workflows where maintaining minimum bend radius is non-negotiable for keeping insertion loss in spec across an entire fiber run.
Key Features
- 19-inch EIA rack compatibility (485.6mm / 19.12 in wide): Fits any standard EIA 19-inch telecom rack without adapters or custom rail spacing. No rack-specific SKU hunting — if it's a standard rack, the FQCRCM drops right in.
- 1U form factor (27.4mm / 1.08 in tall): Occupies exactly one rack unit at the rear. For dense cassette deployments where rear space is already stacked, a 1U profile keeps the cable management overhead minimal.
- Up to 1 meter of slack storage: The integrated cable guide holds up to one meter of cable slack per run. That slack reserve is what lets you re-terminate or re-route a run without pulling new cable — a real labor-cost benefit during moves, adds, and changes in active data centers or IDF closets.
- Bend-radius and tension control in a single unit: By routing cables through a fixed guide path, the FQCRCM enforces the minimum bend radius required by fiber optic specifications. Violated bend radius is one of the top causes of elevated insertion loss in passive optical infrastructure — this removes that risk passively, with no ongoing technician attention required.
- Eliminates horizontal cable managers at the rear: Each FQCRCM replaces what would otherwise require a dedicated horizontal cable manager at the cassette's rear egress. In a fully populated 42U rack, that's real rack unit savings and a cleaner cable plant.
- Black finish: Standard black matches the majority of rack enclosure interiors — no visual mismatch in mixed-vendor rack environments.
- QuickNet system integration: Designed as part of the Panduit QuickNet fiber cassette ecosystem, the FQCRCM works alongside QuickNet cassettes and fiber panels. Buying within the same system means the physical interfaces are engineered to align — no improvised routing solutions needed.
Integration and Compatibility
The FQCRCM is built for fiber optic panel and cassette enclosure deployments in standard 19-inch EIA racks. It is listed under the fiber-optic-systems category, specifically fiber optic panels, cassettes, and enclosure accessories. Competitor cross-reference part numbers E2XHD-CMB and STOK-Q019-00-A01 indicate direct functional equivalency for installers evaluating alternatives.
The unit ships individually (package quantity: 1) and is available in cartons of 10, which makes it practical to stock as a standard build-of-materials item for data center rollouts, IDF closet builds, or structured cabling projects where every cassette shelf gets a rear manager.

Frequently Asked Questions
Q: What rack width does the FQCRCM fit?
A: The FQCRCM is 19.12 inches (485.6mm) wide, designed for standard EIA 19-inch telecommunications racks. It does not require adapters for standard rack installations.
Q: How much cable slack can the FQCRCM hold?
A: The FQCRCM can store up to one meter of cable slack per run. This reserve allows re-termination or re-routing during moves, adds, and changes without pulling new cable.
Q: Does the FQCRCM replace a separate horizontal cable manager?
A: Yes — it mounts at the rear of the rack and organizes and routes cables while storing slack, eliminating the need for a dedicated horizontal cable manager at each cassette rear egress position.
Q: Is the FQCRCM compatible with cassettes from other manufacturers?
A: The FQCRCM is designed as part of the Panduit QuickNet fiber cassette system. Cross-reference part numbers E2XHD-CMB and STOK-Q019-00-A01 are listed as competitor equivalents, indicating functional parity with those alternatives — but verified compatibility with non-Panduit cassettes should be confirmed against your specific cassette enclosure dimensions.
Q: How tall is the FQCRCM in rack units?
A: The FQCRCM is 1.08 inches (27.4mm) tall — a 1U form factor. It mounts at the rear rail of the rack without consuming front rack unit space.
Q: Can I buy the FQCRCM in bulk quantities?
A: Yes. The FQCRCM ships individually (package quantity of 1) and is available in cartons of 10, making it practical to stock for structured cabling projects or data center builds requiring consistent rear cable management across multiple cassette positions.
The FQCRCM gets specified on practically every QuickNet cassette deployment I see — and the reason is the one-meter slack storage spec. That single number is what separates a cable plant you can actually service from one that requires a full re-pull every time a run needs to be re-terminated. In a 10-rack IDF closet with 40+ cassette positions, that's the difference between a two-hour MAC and a two-day project.
Technical Highlights:
- 1U rear profile (27.4mm): Mounts behind the cassette shelf without eating front rack space — critical in high-density builds where every front unit is allocated to active equipment.
- Up to 1m slack storage: Gives enough reserve fiber to re-terminate SC or LC connectors at least once without touching the horizontal run — a direct reduction in future labor cost on any structured cabling project.
- EIA 19-inch fit (485.6mm): No adapter plates, no shimming — drops directly onto standard rear rails. Carton quantity of 10 means you can stock it as a standard BOM line item for rack builds without per-project sourcing.
Deployment Considerations:
- The FQCRCM is rear-mount only — it attaches to the back rails of an EIA 19-inch rack. Verify your rack has accessible rear rail positions before specifying; four-post open-frame racks are ideal, two-post relay racks may require a different approach.
- Designed for the Panduit QuickNet cassette system — while competitor cross-references E2XHD-CMB and STOK-Q019-00-A01 suggest equivalency, physical fit with third-party cassette enclosures should be field-verified before specifying across a full deployment.
For structured cabling teams building out fiber distribution frames in multi-rack IDF or MDF environments — particularly where future MACs are expected — the FQCRCM is the right rear management solution to spec at every cassette position from day one.
