Middle Atlantic NM Fiber Radius Outside E - PN05F19WH

Middle Atlantic PN05F19WH NM Series Outside Fiber Radius Guard

Overview

The PN05F19WH is a white outside fiber radius guard from Middle Atlantic's NM series, engineered to enforce minimum bend radius compliance when routing fiber optic cables through rack infrastructure. Tight corners and sharp redirections in cable pathways are a leading cause of fiber attenuation and long-term signal degradation — this guard physically constrains the bend geometry so installers can't inadvertently kink a run during initial install or future moves-adds-changes. It fits deployments where fiber exits or transitions at rack or panel edges, providing the controlled curve geometry that fiber cable requires without relying on installer judgment alone. The white finish suits white rack or enclosure environments where color coordination matters for clean cable management presentation.

Compatibility

Designed for use with Middle Atlantic's NM series Middle Atlantic rack and enclosure products. The NM series covers a range of modular cable management components — this outside radius guard is the companion piece for outside-corner fiber transitions in that system. Confirm your NM series panel or trough configuration before ordering; inside-radius and outside-radius guards are not interchangeable, and this PN05F19WH is specifically the outside variant. For broader rack accessory compatibility across the NM line, verify panel width and mounting interface against your existing NM hardware. If your installation uses a different Middle Atlantic series, consult the series-specific fiber management components rather than substituting across families.

Installation Notes

Position this guard at outside-corner transition points in your fiber routing path — locations where the cable route bends outward rather than inward. Proper placement ensures the guard bears the bend load rather than the cable jacket. Confirm the fiber type and manufacturer's minimum bend radius spec before finalizing the routing geometry; the guard enforces the physical path, but the fiber's own bend-radius limit remains the governing constraint. No special tooling is documented in available evidence for this component.
