Panduit FRT24X4W12LBL FiberRunner 24x4 Horizontal Tee Fitting

Overview

The Panduit FRT24X4W12LBL is a horizontal tee fitting engineered specifically for the FiberRunner® 24x4 fiber cable routing system — the right component when your pathway design branches at a 90-degree lateral junction and you need a dimensionally matched, standards-compliant solution rather than a field-improvised workaround. Sized at 24.48 in. wide × 4.48 in. tall (621.8 mm × 113.8 mm), this fitting integrates flush with the 24x4 FiberRunner channel, maintaining consistent inside radius protection for fiber strands through every branch point. Designed for data centers and telco central offices, the FRT24X4W12LBL brings the same construction quality and compliance credentials as the rest of the FiberRunner family to your most demanding tee-junction runs.

Key Features

• Dimensional Precision — 24.48 in. × 4.48 in. (621.8 mm × 113.8 mm): An exact dimensional match to the 24x4 FiberRunner channel means no offset misalignment at the junction. Mismatched tees create stress points at fiber entry — the leading cause of insertion-loss creep in dense central office runs. Matching dimensions eliminate that risk from day one.
• Polycarbonate/ABS Construction: Polycarbonate delivers the impact resistance needed in active cable management environments where technicians are routinely pulling adjacent runs. ABS contributes dimensional stability under varying thermal loads — important in data center hot-aisle/cold-aisle environments where localized temperatures can vary significantly across a single rack row.
• UL Listed to 2024A — Optical Fiber Cable Routing Assemblies: UL 2024A listing confirms this fitting has been independently evaluated to the standard governing optical fiber routing assemblies — a requirement on most enterprise and telco projects where AHJ sign-off demands listed components throughout the pathway, not just at terminal equipment.
• Telcordia GR-63-CORE Network Equipment Building System Level 3 Compliance: GR-63-CORE Level 3 is the seismic and environmental robustness benchmark for central office network equipment. Compliance here means the fitting is validated against vibration, seismic zone, and environmental stress profiles that reflect real telco facility conditions — not just office-grade equivalents.
• RoHS Compliant: RoHS compliance keeps this component aligned with environmental procurement requirements on public-sector and international projects where restricted substance documentation is mandatory at the bill-of-materials level.
• Black Finish — Consistent Pathway Aesthetics: Matches standard FiberRunner black channel color throughout the tee junction. Consistent color coding simplifies visual pathway identification during audits and maintenance, particularly in high-density data center environments where distinguishing fiber from copper pathways at a glance reduces the chance of incorrect cable pulls.
• Overall Length 29.96 in.: The tee body's 29.96 in. footprint accounts for the full branch geometry — confirm overhead ladder or tray clearance in your elevation plan before specifying multiple tees in adjacent runs. In tight interstitial spaces this dimension determines whether the fitting can be installed without obstruction from adjacent pathways or structural steel.
• Sold Individually (Package Qty: 1): Ordered and priced per unit, so project BOM quantities map directly to junction count — no minimum-pack overstock to manage.

Integration & Compatibility

The Panduit FiberRunner system is a modular fiber cable management platform built around consistent cross-sections. The FRT24X4W12LBL is designed for use exclusively with the 24x4 FiberRunner system — the 24-inch-wide, 4-inch-tall channel family. It is not dimensionally compatible with 4x4, 6x4, 12x4, or other FiberRunner cross-sections. Before specifying, verify your installed or planned channel is the 24x4 series throughout the run. Panduit identifies the competitive equivalent as FGSB-MHRT-H/F, which can assist in cross-referencing existing infrastructure documentation or replacement scenarios where a competitor component is already specified.

This fitting integrates with the broader fiber routing and management ecosystem — pair it with FiberRunner straight sections, elbows, reducers, and covers to complete a fully enclosed, bend-radius-controlled fiber pathway. For data center deployments, consider mapping the complete pathway before ordering fittings: tee count, elbow count, and straight-section lengths all need to be captured upfront since each fitting type is a separate SKU in the FiberRunner catalog.

Frequently Asked Questions

Q: Is the FRT24X4W12LBL compatible with FiberRunner channels other than the 24x4 series?

A: No. The FRT24X4W12LBL is dimensioned specifically for the Panduit 24x4 FiberRunner system (24.48 in. wide × 4.48 in. tall). It is not interchangeable with 4x4, 6x4, 12x4, or any other FiberRunner cross-section. Verify your channel series before ordering.

Q: What standards does the FRT24X4W12LBL meet?

A: It is RoHS Compliant, UL Listed to 2024A for Optical Fiber Cable Routing Assemblies, and compliant with the applicable tests in Telcordia GR-63-CORE Network Equipment Building Systems Level 3.

Q: What material is the FRT24X4W12LBL made from?

A: Polycarbonate/ABS blend — polycarbonate for impact resistance and ABS for dimensional stability under thermal variation, both relevant in active data center and central office environments.

Q: What are the overall dimensions of the FRT24X4W12LBL?

A: Overall width is 24.48 in. (621.8 mm), overall height is 4.48 in. (113.8 mm), and overall length is 29.96 in. Plan for the 29.96 in. footprint when assessing clearance in overhead or under-floor pathways.

Q: How many units come in a package?

A: The FRT24X4W12LBL ships as a single unit (Package Qty: 1), so order quantity equals your junction count directly.

Q: What is the competitive cross-reference for this fitting?

A: Panduit identifies the competitive equivalent as FGSB-MHRT-H/F for cross-referencing purposes in replacement or mixed-infrastructure scenarios.

Ted Perry

When I spec horizontal tees for 24x4 FiberRunner runs, the first thing I confirm is the GR-63-CORE Level 3 compliance — the FRT24X4W12LBL carries it, which matters the moment the project scope includes a telco central office or a data center with seismic zone requirements. That compliance isn't cosmetic; it reflects real mechanical validation that this fitting won't compromise pathway integrity under the vibration and seismic stress profiles defined in the standard.

Technical Highlights:

• Overall Length 29.96 in.: The tee body is nearly 2.5 feet long end-to-end — always plot this against overhead structural steel, cable tray neighbors, and HVAC before finalizing your pathway elevation. In tight interstitials, a 29.96 in. fitting requires clear run-in on both the straight-through and branch legs simultaneously.
• Polycarbonate/ABS Material: Polycarbonate handles the impact loading from active maintenance pulls on adjacent runs; ABS keeps the fitting from warping dimensionally in the thermal cycling you see across a data center floor. For a fitting this wide (24.48 in.), material dimensional stability directly affects how cleanly it aligns with adjacent straight sections over time.
• UL 2024A Listing: AHJ sign-off on enterprise and telco projects routinely requires listed fiber routing components throughout — not just at patch panels. This listing keeps the FRT24X4W12LBL compliant on projects where an unlisted tee would trigger a field non-conformance notice.

Deployment Considerations:

• Order tee quantity based on a finalized pathway elevation drawing — the 29.96 in. body length means late-stage pathway reroutes can strand inventory, and this is a per-unit SKU with no multi-pack buffer.
• Confirm the installed channel throughout the run is 24x4 series before placing the order. The FiberRunner catalog has multiple cross-sections and the fittings are not cross-compatible — a 12x4 run sharing the same ceiling zone requires a different tee SKU entirely.

The FRT24X4W12LBL is the right specification for a hyperscale or carrier-class data center build where the fiber pathway must satisfy both UL 2024A AHJ requirements and Telcordia GR-63-CORE Level 3 seismic compliance — that combination of certifications is what separates this from generic tray fittings in critical infrastructure bids.
