Middle Atlantic 837TCAL-NK Carpet Tile Cable Flange

The 837TCAL-NK is a carpet tile cable flange from Middle Atlantic, built to pass cabling through a raised-access-floor tile without leaving a ragged cutout exposed. It measures 10.5" x 16" x 0.63" (266.7 x 406.4 x 16.1 mm) and ships in the NK (nickel) finish. If you're running cable drops up through carpet tile in a conference room, data center perimeter, or AV floor box installation, this is the trim piece that keeps the penetration point clean and walkable.

Overview

837TCAL-NK is a flush-mount flange designed to sit within a cut carpet tile section, framing the opening where cabling exits the raised floor plenum. The low 0.63" profile is shallow enough to sit near-flush with standard carpet tile thickness, reducing trip-hazard height at the cable exit point. Middle Atlantic lists this SKU as TAA compliant, which matters for integrators bidding federal, municipal, or other government-funded builds that require Trade Agreements Act sourcing documentation.

Key Features

• 10.5" x 16" footprint: sized to fit within a standard carpet tile cut, so you're not improvising a larger hole than the flange can cover.
• 0.63" (16.1mm) low profile: keeps the flange close to floor level, minimizing the lip that foot traffic or rolling equipment carts would otherwise catch on.
• Nickel (NK) finish: a neutral metallic finish that reads as intentional trim rather than a patched cutout in a finished space.
• TAA compliant: supports government and public-sector procurement requirements where Trade Agreements Act sourcing has to be documented on the bid.

Integration & Compatibility

As a cable pass-through flange, the 837TCAL-NK pairs naturally with under-floor cabling runs feeding network video recorders, rack equipment, or AV endpoints in a raised-floor room. If you're planning a broader structured cabling layout for the space, a PoE and cabling planning guide is worth a pass before finalizing floor penetration points, since flange placement should follow conduit and drop locations rather than the other way around. For the rack or enclosure the cabling ultimately feeds, check the rest of the Middle Atlantic catalog for matching rack accessories.

The 837TCAL-NK is a small part that saves you from a sloppy-looking floor cutout on a raised-floor install. At 10.5" x 16" and only 0.63" thick, it's sized to sit inside a standard carpet tile section without proud edges catching a cart wheel.

Technical Highlights:

• 10.5" x 16" x 0.63" profile: low enough to keep the flange close to floor height, so it doesn't become a trip point in a walked area.
• Nickel finish: matches neutral commercial floor trim rather than standing out as an obvious patch.
• TAA compliance: lets this line item go on a federal or public-sector bid without a sourcing exception.

Deployment Considerations:

• Confirm your carpet tile thickness against the 0.63" flange depth before cutting — you want the flange sitting flush, not proud of the surrounding tile.
• This is a passive trim part with no cable capacity rating in the available documentation, so plan bundle size and conduit routing separately.

Reach for the 837TCAL-NK when you're finishing a raised-floor conference room or data hall walkway where cabling has to come up through carpet tile and the client expects a clean, walkable finish rather than a visible cutout.
