Middle Atlantic NM Spacer 5500 White - 5507S-WH

Middle Atlantic 5507S-WH Non-Metallic Rectangular Spacer Fitting

Overview

The Middle Atlantic 5507S-WH is a non-metallic spacer fitting designed for use with the 5500 series rectangular raceway system. This white fitting bridges gap sections in the raceway run, maintaining a clean, continuous appearance in finished interior environments — drop ceilings, server rooms, office walls, and AV equipment rooms where exposed wiring management is visible to end users. TAA-compliant for federally funded projects and government installations requiring Buy American Act conformance.

Compatibility

Designed for use with the Middle Atlantic 5500 series non-metallic rectangular raceway system. Pairs with 5500 series base, cover, inside corners, outside corners, and end caps within that product family. Not intended for use with the 5400 or 6000 series raceways — verify fitting series before ordering. For broader cable management planning including conduit and horizontal organizers, confirm that the 5500 series raceway dimensions match your existing run before adding spacers.

Installation Notes

Mounts to standard drywall, masonry, and finished surfaces consistent with the 5500 series base installation. Non-metallic construction — no grounding path through the fitting itself; ensure your installation's grounding continuity is achieved through other means if required by code. White finish matches the standard 5500-WH series components. TAA compliance makes the 5507S-WH eligible for government and institutional AV and security infrastructure projects where country-of-origin documentation is required.
