The Middle Atlantic 828DLR is a single locking cover plate designed for concrete floor box installations. At 3.13 in wide by 4.13 in deep and a profile of just 0.25 in tall, it sits nearly flush with the finished floor surface — reducing trip hazard exposure in high-foot-traffic areas such as conference rooms, corporate lobbies, and open-plan office floors where floor box access points need to stay unobtrusive when not in active use. The brass finish is a common specification in commercial and hospitality environments where cover hardware needs to coordinate with architectural finishes rather than clash with them.
If you are sourcing replacement covers for an existing Middle Atlantic floor box assembly, or specifying covers for a new concrete floor box rough-in, confirm that the floor box model accepts a single-gang locking cover in these footprint dimensions before ordering.
This cover plate is designed for use with Middle Atlantic concrete floor box systems. No compatibility data beyond the physical footprint is available in the manufacturer's published specifications. Cross-reference your floor box model number against Middle Atlantic's current product matrix to confirm cover plate interchangeability before ordering in quantity. For AV infrastructure deployments, verify that the cover plate opening accommodates the insert modules or receptacles planned for the floor box assembly.
Q: Is the Middle Atlantic 828DLR TAA compliant?
A: No. The 828DLR is explicitly listed as not TAA compliant. Federal projects or bids with TAA requirements must use a different cover plate.
Q: What are the dimensions of the 828DLR?
A: The 828DLR measures 3.13 in (8 cm) wide, 4.13 in (10.5 cm) deep, and 0.25 in (0.6 cm) tall — a near-flush profile above the finished floor surface.
Q: What finish does the 828DLR come in?
A: Brass. No other finish variants are listed in the manufacturer's specifications for this model number.
Q: Is the 828DLR a locking cover?
A: Yes. It is a single locking cover plate, which keeps the floor box secured when receptacles or inserts are not in active use.
Q: What type of floor box does the 828DLR fit?
A: The 828DLR is designed for concrete floor box applications. Confirm your specific floor box model accepts a single-gang cover in the 3.13 in x 4.13 in footprint before ordering.

The 828DLR is a straightforward brass single locking cover plate with a 0.25 in standing height — the spec that matters most when you are finalizing a floor box rough-in in a finished commercial space. That near-flush profile is not incidental; it is the primary reason integrators specify brass locking covers over generic steel in lobbies and boardrooms where aesthetics and trip-hazard liability both factor into the hardware selection.

Deployment Considerations:
The 828DLR is the right cover plate for commercial interior deployments — corporate conference rooms, hotel meeting spaces, and executive suites — where brass hardware is on the finish schedule and the floor box needs to disappear into the floor when it is not in use.
