Middle Atlantic Aluminum Designer Series - ALDS4000B

Middle Atlantic ALDS4000B Aluminum Designer Series Raceway Base

Overview

The Middle Atlantic ALDS4000B is an aluminum raceway base from the Middle Atlantic cable management line — built for clean, professional cable routing in commercial AV and security installations where exposed wiring is not acceptable. At 12 inches wide, 5.5 inches tall, and 2 inches deep, this raceway provides meaningful interior capacity for bundling power, data, and low-voltage cabling along walls and ceilings without the bulk of a full wireway enclosure.

TAA compliance makes the ALDS4000B a viable choice for federal, state, and municipal projects subject to the Trade Agreements Act — a requirement that eliminates many commodity cable management alternatives from government bid lists. If your project involves government facilities or GSA schedule purchases, this certification matters at the specification stage, not as an afterthought.

Aluminum construction keeps weight low while maintaining the rigidity needed to support cable bundles over long runs. Unlike PVC raceways that can warp under heat load or discolor over time in high-ambient environments, aluminum holds its form and finish — relevant in any space where the raceway is visible and aesthetics are part of the deliverable.

Key Features

• 12-inch width (30.5 cm): Wide enough to route multiple cable categories — structured cabling, coax, and low-voltage control runs — in a single raceway without forcing tight bend radii that degrade signal integrity on Cat6A or RG-6.
• 5.5-inch height (14 cm): Provides vertical interior clearance for cable management accessories such as dividers or separators that isolate high-voltage from data cabling per NEC requirements.
• 2-inch depth (5.1 cm): Shallow enough to mount flush against standard wall surfaces without projecting into traffic paths — critical in corridors, server rooms, and retail environments where wall projection is a safety or aesthetic concern.
• TAA Compliant: Meets Trade Agreements Act requirements, opening this product to federal procurement vehicles and government integrator bids that mandate domestic or TAA-country-of-origin products.
• Aluminum construction: Resists warping and discoloration in elevated-temperature environments — appropriate for above-ceiling runs near lighting or mechanical equipment where PVC alternatives degrade.
• Designer Series finish: Intended for visible installations where cable management is part of the finished appearance — conference rooms, executive offices, lobbies, and public-facing security desk deployments.

Integration and Compatibility

The ALDS4000B is designed as part of the Middle Atlantic ALDS4000 series raceway system. As a base component, it pairs with matching raceway covers and fittings from the same series — inside corners, outside corners, couplers, and end caps — for a complete, finished installation. Verify series-specific fitting compatibility before ordering accessories; mixing raceway generations can result in gaps or misaligned cover profiles that compromise both appearance and cable protection.

For security infrastructure deployments, this raceway suits runs between PoE network switches and IP camera mounting locations, or between access control panels and door hardware, where a finished cable management solution is specified. It is not a conduit substitute for NEC Article 358 applications — confirm with your AHJ whether raceway or conduit is required for your jurisdiction and cable type before spec-ing this product.

Frequently Asked Questions

Q: Is the ALDS4000B TAA compliant?

A: Yes. The ALDS4000B is TAA compliant, making it eligible for federal government procurement and GSA schedule projects that require Trade Agreements Act country-of-origin compliance.

Q: What are the dimensions of the ALDS4000B?

A: The ALDS4000B measures 12 inches wide (30.5 cm), 5.5 inches tall (14 cm), and 2 inches deep (5.1 cm).

Q: What is the ALDS4000B made of?

A: It is constructed from aluminum, which provides rigidity and resistance to warping or discoloration compared to PVC alternatives — suitable for environments with elevated ambient temperatures.

Q: Does the ALDS4000B require matching covers and fittings from the same series?

A: Yes. The ALDS4000B is a base component in the Middle Atlantic ALDS4000 series. Covers, corners, couplers, and end caps should be sourced from the same series to ensure proper fit and a finished appearance.

Q: Is the ALDS4000B suitable for use as electrical conduit?

A: No. This is a surface raceway, not a listed conduit. Confirm with your authority having jurisdiction (AHJ) whether raceway or conduit is required for your specific cabling type and installation environment before specifying this product.

Ted Perry

The ALDS4000B sits in a specific niche: it is a large-format aluminum surface raceway base — 12 inches wide and 5.5 inches tall — intended for visible commercial runs where a clean finished look is non-negotiable and TAA compliance is a bid requirement. I specify it when PVC raceways are ruled out by environment or procurement rules.

Technical Highlights:

• 12 in x 5.5 in interior profile: Enough volume to segregate structured cabling from coax or low-voltage control wiring using internal dividers — reduces interference and keeps the installation NEC-tidy without running parallel raceways.
• 2-inch depth: Mounts close to the wall surface, which matters in corridors with ADA clearance requirements or in finished spaces where projection is an aesthetic problem.
• TAA compliance: Puts this product on the short list for government facility integrators — a meaningful differentiator when bid specs call out TAA and eliminate non-compliant alternatives at the spec stage.

Deployment Considerations:

• The ALDS4000B is a base-only component — budget for series-matched covers, inside/outside corners, and couplers. Failing to order the full fitting set is the most common field delay on raceway jobs.
• Aluminum raceways can conduct if grounding is not addressed; verify bonding requirements with your AHJ, especially in installations that route low-voltage alongside any higher-voltage circuits.

This is the right call for lobby-level or executive-suite security infrastructure runs — access control wiring, IP camera drops, intercom cabling — where the raceway is visible and the client expects a finished, architectural result, not a conduit-gray utility look.
