Middle Atlantic 2451H-BK Back Feed Fitting

The 2451H-BK is a black steel back feed fitting from Middle Atlantic, built for routing cable and power feeds behind raceway and wireway runs in commercial AV and low-voltage installs. At 0.27 lbs, it's a small hardware component, but the model number 2451H-BK matters at order time — Middle Atlantic sells this fitting across multiple finish and configuration variants, and specifying 2451H-BK (often searched as 2451H BK) is how you make sure the black finish version lands on your truck instead of a different color or fitting style.

Key Features

• Steel construction: Steel resists the physical wear a fitting takes during pull-through and re-termination work, holding up better under repeated cable changes than a plastic equivalent.
• Black finish: Matches black raceway, wireway, and rack hardware runs so the fitting doesn't stand out against surrounding infrastructure in a finished install.
• Back feed configuration: Lets you bring cable or power into a run from behind the mounting surface rather than through a visible front opening, which keeps the face of the installation clean in customer-visible spaces like conference rooms and lobbies.
• 0.27 lb weight: Light enough that it adds negligible load to a wireway run or rack assembly, and keeps shipping costs down when ordering in quantity for a multi-room rollout.
• Made in the United States: Domestic manufacturing supports NDAA and Buy American sourcing requirements that show up in government and education bid specs.

Integration & Compatibility

The 2451H-BK is built to work within Middle Atlantic's wireway and raceway hardware line, where fittings, connectors, and back feed components are designed to share a common form factor. If you're speccing a full cable management run, check it against the rest of the Middle Atlantic catalog and the broader mounts and racks category for matching wireway sections and connector fittings before you finalize a bill of materials. For AV integrators laying out a rack room or credenza install, a PoE and cable planning guide is worth a read before you commit to fitting placement, since back feed points are easiest to plan before conduit and wireway are cut. Pair the fitting with compatible rack accessories if you're finishing out a full enclosure.

The 2451H-BK is one of those parts that never gets specced with excitement, but it's the fitting that decides whether your wireway run looks clean or looks like an afterthought. Steel body, black finish, 0.27 lbs — small footprint, straightforward job.

Technical Highlights:

• Steel body: Holds up to repeated cable pulls and re-terminations better than a molded plastic fitting would over the life of an install.
• Black finish: Matches black wireway and rack hardware so the back feed point doesn't visually interrupt a finished run.
• 0.27 lb weight: Adds almost nothing to load calculations on a wireway assembly, which matters when you're stacking multiple fittings across a long run.

Deployment Considerations:

• Confirm the 2451H-BK's back feed opening matches the wireway or raceway section you're pairing it with before ordering in bulk — fitting families in this space are not universally interchangeable across manufacturers.
• Because this is a small hardware component with no listed dimensions beyond weight, verify physical clearance behind your mounting surface before you commit to a back-feed layout rather than a front-feed one.

Good fit for a conference room or credenza AV install where the wireway run is black and front-of-house appearance matters — the 2451H-BK keeps the feed point out of sight without swapping to a different fitting color partway through the job.
