Steel City 698 Floor Sub-Plate

The Steel City 698 Floor Sub-Plate is a single-gang brass component designed for floor-box installations. It provides a secure mounting point for compatible covers in residential or commercial settings. Electricians and installers working with P64 floor plate covers will find this part matches their requirements. Buyers needing multi-gang configurations should select a different model.

Behaviour under sustained load

The brass construction resists corrosion and maintains structural integrity when subjected to regular foot traffic and environmental exposure. Its material properties help ensure consistent electrical grounding over extended periods. The round shape distributes pressure evenly across the mounting surface. No performance degradation is expected under normal floor-box operating conditions.

Build quality and daily implications

The solid brass body offers durability and a clean appearance that suits finished flooring. A 1 7/16 inch conduit opening aligns with standard fittings for straightforward installation. Compatibility with P64 covers simplifies the selection of matching faceplates. The transparent color designation in the specifications may refer to a protective coating rather than the visible brass finish.

Questions about this item

Does the brass construction of the 698 sub-plate generate noticeable heat or noise when installed in a floor box?

No, this is a passive brass component with no electrical or moving parts, so it produces no heat or noise during operation.

Which specific floor plate covers must I already own for the 698 sub-plate to fit correctly?

It is designed for use with P64 floor plate covers, so you need those covers for proper installation.

Will the 698 sub-plate work with older Steel City floor boxes that use the same 1 7/16 in conduit size?

Yes, the 1 7/16 in conduit size matches the specification, allowing it to fit compatible older boxes.
