Panduit FRTR4X4LBL FiberRunner 4x4 Bend Radius Control Trumpet
Overview
The Panduit FRTR4X4LBL is a bend radius control trumpet designed for use with the FiberRunner® 4x4 cable routing system in data centers and telco central offices. Its singular job: enforce a minimum 2-inch (50.4 mm) bend radius on fiber and copper cables at every channel exit point — the kind of discipline that prevents signal degradation and physical damage in high-density routing environments where cable management corners are cut under pressure. If you're running structured fiber through a 4x4 FiberRunner channel or a 4x4 horizontal tee and need compliant, consistent egress geometry, this is the fitting that closes that gap.
Built from polycarbonate/ABS and finished in black, the FRTR4X4LBL is engineered to integrate directly with Panduit FiberRunner cable management systems, providing a three-sided bend radius control profile at spillout points. It ships as a single unit (package quantity: 1) with carton quantities of five for project-scale procurement.
Key Features
- 2-Inch Minimum Bend Radius Enforcement: Fiber optic cable bent too tightly at channel exits is one of the most common sources of insertion loss in structured cabling installations. The FRTR4X4LBL constrains cable to a 2-inch (50.4 mm) radius at the exit point — keeping you within the minimum bend radius specification for virtually all standard single-mode and multimode fiber types without having to engineer a custom transition.
- 4x4 FiberRunner System Compatibility: Designed specifically for use with the 4x4 channel and 4x4 horizontal tee in the FiberRunner cable routing system. This is not a universal fitting — it mates to that specific channel profile, which means you get a clean mechanical fit without shimming, taping, or field modification.
- Polycarbonate/ABS Construction: This material pairing gives you the rigidity of polycarbonate with the impact resistance of ABS. In a data center environment where cable trays get bumped during maintenance, the fitting holds its geometry rather than cracking or deforming — which matters because a deformed trumpet defeats its own bend radius purpose.
