Middle Atlantic Brass CPT Comb PLT 21/4 P - 896CK

Middle Atlantic 896CK Brass CPT Comb Cover Plate

Overview

The Middle Atlantic 896CK is a replacement or supplemental cover plate designed for the 881-series Ratchet Pro raised floor box system. At 5.5 in × 5.5 in with a 0.25 in installed height, the 896CK sits nearly flush with finished flooring surfaces — keeping cable egress organized without creating a trip hazard. The comb plate configuration manages cable routing at the floor box opening, making it the right component for structured cabling and AV/communications deployments where multiple conductors need to exit a single floor box cleanly.

Compatibility

The 896CK is designed for the Middle Atlantic 881-series Ratchet Pro raised floor boxes, specifically the communications and power cover plate opening. Verify your floor box model is within the 881-series before ordering — the 5.5 in footprint and ratchet retention mechanism are specific to that family. This plate is not a universal fit for other Middle Atlantic floor box lines. If you are wiring a mixed AV and low-voltage security installation through a raised floor, pair this cover with the appropriate 881-series base and any cable management accessories needed for the cable count in your conduit path.

Installation Notes

The 896CK mounts into an 881-series floor box lid opening using the integrated ratchet locking mechanism — no additional hardware required for the plate itself. The 0.25 in height profile means it contributes negligible floor buildup once seated. Brass construction provides durability at the floor level where plastic alternatives wear quickly under foot traffic and rolling equipment. TAA compliance is not applicable for this component. Confirm cable diameter and count against the comb slot dimensions before install to ensure cables route without binding.
