Panduit FRTR6X4LBL FiberRunner Bend Radius Control Trumpet
The Panduit FRTR6X4LBL enforces a 3-inch minimum bend radius at 6×4 FiberRunner channel exits and horizontal tee terminations — preventing the cable kinking that destroys fiber cores during breakout installations. Telecordia GR-63-CORE Level 3 certified and UL 2024A listed for optical fiber routing assemblies, this trumpet guides multi-fiber trunks through the critical transition from enclosed raceway to open pathways without stress-induced attenuation or physical damage to fragile glass strands.
Key Features
- Enforces 3 in (76.2 mm) minimum bend radius at 6×4 channel exits
- Polycarbonate/ABS construction for impact resistance in high-density pathways
- UL 2024A listed optical fiber cable routing assembly
- Telecordia GR-63-CORE Level 3 compliant for telco/data center environments
- 10.89 in wide flare accommodates breakout from 6×4 channel or horizontal tee
Fiber breakout points are the failure zone in structured cabling — the transition from protected channel to open routing exposes cables to installer force and sharp-angle pulls that exceed manufacturers' 10× cable-diameter bend-radius minimums. The FRTR6X4LBL trumpet's flared geometry physically blocks bends tighter than 3 inches, distributing stress across the cable jacket rather than concentrating it at the optical core. This matters for OS2 single-mode and OM3/OM4 multimode trunks feeding 40G/100G aggregation switches where a single kinked fiber can drop an entire uplink. The 5.96-inch height provides gradual angle transition for cables exiting vertically or horizontally from FiberRunner 6×4 pathways.
Polycarbonate/ABS blend construction survives the tool drops and rack collisions common in live data-center hot-aisle work — the trumpet won't crack when a ladder leans against the channel or a technician's elbow catches the flare during adjacent-rack maintenance. Black finish matches Panduit's FiberRunner ecosystem for clean visual integration in glass-walled NOCs and customer-facing MDF/IDF spaces. The trumpet mounts directly to 6×4 FiberRunner channel ends or the outlet ports of 6×4 horizontal tees, creating a continuous protected pathway from backbone risers through horizontal distribution to equipment connections.
UL 2024A listing certifies flame-propagation and smoke-generation characteristics for plenum and riser installations, while Telecordia GR-63-CORE Level 3 compliance validates performance under the thermal cycling, vibration, and seismic conditions specified for NEBS (Network Equipment Building System) Level 3 telco facilities. RoHS compliance ensures the trumpet meets EU and California electronic-waste restrictions for data centers with international operations or procurement policies tied to environmental certifications. Ships as single unit (5 per carton for stocking distributors) ready for field installation without additional hardware beyond the base FiberRunner mounting clips.
