Middle Atlantic STL Raceway Base 10FT G40 - G4000B-10

Middle Atlantic G4000B-10 Steel 4000 Series 10 ft Raceway Base

Overview

The Middle Atlantic G4000B-10 is the base channel of the 4000 Series steel raceway system, designed to organize and protect cabling in commercial AV, security, and structured-wiring installations. At 10 feet long, 12 inches wide, and 4.75 inches tall, each run covers substantial horizontal distance without requiring frequent splice points — useful when routing multiple cable bundles across open wall spans in server rooms, control centers, or surveillance head-end closets. If you are deploying Middle Atlantic rack and cable management systems, the G4000B-10 base pairs with the matching cover to form a complete enclosed channel. The model number G4000B-10 (often searched as G4000B 10) calls out the 10-foot base length, differentiating it from shorter cuts in the same family.

Key Features

• 12-Inch Interior Width: At 12 in (30.5 cm) across, this raceway accommodates high-density cable bundles — think parallel runs of Cat6, coax, and low-voltage control wiring side by side without forced bending or tight packing that degrades signal integrity.
• 4.75-Inch Channel Depth: The 4.75 in (12.1 cm) profile provides meaningful vertical clearance inside the channel, giving installers room to hand-lay and dress cables cleanly rather than stuffing them in. This matters on longer runs where pull tension and cable management labor add up.
• 1.63-Inch Mounting Depth: The base itself sits only 1.63 in (4.1 cm) off the wall surface, keeping the assembly tight to the wall and avoiding protrusion into walkways or equipment clearance zones — relevant in machine rooms and data closets where every inch of aisle space counts.
• 10-Foot Run Length: A single G4000B-10 spans 10 feet, reducing the number of splice joints across a long wall run. Fewer joints means less installation time and fewer potential weak points in the raceway assembly.
• Steel Construction, Gray Finish: Cold-rolled steel provides the structural rigidity needed for commercial cable management environments where raceway may be bumped by carts or equipment. The gray finish matches standard IT and AV infrastructure aesthetics without requiring paint.
• TAA Compliant: The G4000B-10 is TAA (Trade Agreements Act) compliant, making it eligible for federal government projects, GSA schedule procurement, and any deployment requiring Buy American or TAA-origin products — a hard gate on many government and quasi-government contracts that eliminates non-compliant alternatives from consideration outright.

Integration and Compatibility

The G4000B-10 is the base component of the Middle Atlantic 4000 Series steel raceway. It is designed to be paired with the corresponding 4000 Series cover to form a fully enclosed cable channel. When planning a complete run, account for the matching cover SKU, end caps, and any required connectors or mounting accessories from the same series. This raceway integrates naturally with rack-based network cabinets and AV racks as a surface-mount horizontal feed path, routing structured cabling from patch panels or head-end equipment to field devices. Its steel construction is compatible with standard raceway mounting hardware and can be grounded per local code requirements, relevant in security and low-voltage installations where ground continuity matters. For large-scale deployments, review cable management planning guides to size total raceway capacity before ordering.

Frequently Asked Questions

Q: Is the G4000B-10 TAA compliant?

A: Yes. The G4000B-10 is confirmed TAA (Trade Agreements Act) compliant, making it eligible for federal procurement and GSA schedule contracts.

Q: What are the interior dimensions of the G4000B-10 raceway base?

A: The channel is 12 inches wide, 4.75 inches tall (interior channel height), and 1.63 inches in mounting depth. The run length is 10 feet.

Q: Does the G4000B-10 include a cover?

A: The G4000B-10 is the base channel only. A separate 4000 Series cover is required to enclose the raceway. Verify the matching cover SKU from Middle Atlantic before ordering.

Q: What is the G4000B-10 made of?

A: Steel construction with a gray finish, consistent with Middle Atlantic's 4000 Series commercial-grade raceway line.

Q: Can the G4000B-10 be used in government installations?

A: Yes. TAA compliance makes this raceway base eligible for government and federal agency projects where Trade Agreements Act sourcing is required.

The detail I always flag on the G4000B-10 is the 12-inch channel width paired with the 4.75-inch interior height — that cross-section is genuinely roomy by commercial raceway standards, and it makes a practical difference when you're pulling Cat6A alongside coax and alarm wire on the same run. At 10 feet per base section, you're minimizing splice count on a typical 20–30 foot wall span, which cuts both labor and long-term maintenance headaches.

Technical Highlights:

• 12 in Channel Width: Accommodates parallel high-density cable bundles — Cat6, coax, and low-voltage control — without forced tight bends that degrade signal performance over time.
• 4.75 in Interior Height: Enough vertical clearance to hand-dress cables cleanly inside the channel, reducing re-pull labor on future moves, adds, and changes.
• TAA Compliance: Hard-gate qualifier for federal and GSA projects — eliminates procurement risk on government-funded security and AV installations where origin compliance is non-negotiable.

Deployment Considerations:

• The G4000B-10 is base-only — budget and order the matching 4000 Series cover separately before scheduling installation. Arriving on site without covers is a common delay on first-time orders.
• At 1.63 in mounting depth, verify wall clearance in tight machine rooms before committing to this series; in very constrained spaces a shallower raceway profile may be more practical.

Best fit for TAA-required government facilities, large commercial AV head-end rooms, and security operations centers where wide cable bundles and clean long-run organization justify steel raceway over wire duct.
