Middle Atlantic Brass Data Slide PLT - 829STC

Middle Atlantic 829STC Brass Data Slide Cover Plate

Overview

The Middle Atlantic 829STC is a brass data slide cover plate designed for concrete floor box installations where low-profile, durable port access is required. At 3.25 in wide, 4.25 in deep, and just 0.5 in tall, the 829STC sits nearly flush with the finished floor — keeping cable pathways accessible without creating a trip hazard or snagging point in active workspace environments such as conference rooms, trading floors, or AV-integrated meeting spaces. If you're finishing a concrete floor box run for data or AV signal routing, this cover plate is the termination point that keeps the install clean and professional.

Compatibility

The 829STC is engineered for use with Middle Atlantic concrete floor box systems in the Legrand AV floor box line — specifically the 829STC communications cover plate position within that series. Verify your floor box model accepts a data slide plate in the 3.25 in x 4.25 in footprint before ordering; not all floor box configurations or cover plate positions within the Middle Atlantic line share the same plate opening dimensions. For structured cabling and network accessory deployments integrating floor boxes into a broader Middle Atlantic infrastructure layout, confirm the cover plate position count and orientation match your box model's spec sheet.

Installation Notes

The 829STC is TAA non-compliant — if your project requires TAA-compliant components throughout (federal contracts, GSA schedules), source an alternative cover plate that meets that requirement. The 0.5 in height keeps the plate recessed appropriately for standard finished concrete or raised-floor applications, but verify finished floor depth against the box collar height before installation to ensure the plate sits flush rather than proud of the surface.
