Middle Atlantic Single Gang Cover 3 Tracj - SGT-3TJ

Middle Atlantic SGT-3TJ Single-Gang Aluminum Cover Plate for Three TracJack Inserts

Overview

The SGT-3TJ is a single-gang aluminum cover plate from Middle Atlantic's Wiremold AF-Series, designed to terminate 3-track floor box openings with three Ortronics TracJack inserts. It solves a specific finishing problem in commercial floor box installations: once your cabling is run and your TracJack modules are punched down, you need a rigid, flush-mount face that holds all three inserts securely in a single-gang cutout. The SGT-3TJ is that plate — nothing more, nothing less. If your floor box rough-in is sized for a single-gang 3-track opening with through-floor cable entry, this is the correct cover.

Compatibility

The SGT-3TJ is designed for use with Middle Atlantic Wiremold AF-Series floor boxes configured for single-gang, 3-track openings. It accepts exactly three Ortronics TracJack inserts — the modular snap-in keystone-style modules used across the TracJack product line for Cat5e, Cat6, Cat6A, fiber, HDMI, USB, and other media types. This plate does not accommodate standard keystone jacks outside the TracJack form factor, and it is not compatible with 1-track (SGT-1TJ) or 2-track (SGT-2TJ) configurations. Verify your floor box and cover accessories rough-in gang count and track count before ordering — a 3-track single-gang opening is required. Material is aluminum, consistent with the AF-Series commercial-grade construction standard for environments where a steel or plastic cover would be considered a downgrade.

Installation Notes

Cable entry is through-floor, so route conductors prior to seating the cover. Seat each Ortronics TracJack insert into the three openings before or after positioning the plate, depending on conductor slack. The rectangular aluminum form factor drops into the single-gang recess of the AF-Series floor box assembly — no special tooling is called out in the evidence. Confirm the floor box assembly is fully recessed and flush before final install to avoid a proud edge that becomes a trip or ADA compliance issue in pedestrian traffic areas.
