Middle Atlantic L5 Series Flat Frame L5-FLATFR-43LDW 43IN W 2 Bays

Middle Atlantic L5-FLATFR-43LDW Flat Frame Rack Enclosure, 24RU, 43-Inch Wide, 2-Bay

Overview

The Middle Atlantic L5-FLATFR-43LDW is a 24RU, 43-inch-wide flat frame rack enclosure designed for AV integration, security operations, and technical furniture installations where you need a structured, open-frame chassis with real rack capacity. Part of the Middle Atlantic rack and enclosure line, this flat frame ships domestically only and carries TAA compliance — making it straightforward to spec into government, education, or federal facilities projects without triggering procurement headaches.

At 41.5 inches wide (105.4 cm) and 28.31 inches deep (71.9 cm), the L5-FLATFR-43LDW is sized for dual-bay configurations where you're mounting monitors alongside racked equipment — a common layout in security operations centers, AV control rooms, and command consoles. The 2-bay split gives integrators room to separate display hardware from active electronics, keeping airflow paths cleaner and cable runs more manageable.

Key Features

• 24 Rack Units of usable capacity: 24RU across a 21-inch usable height (53.3 cm) gives you room for a full complement of NVRs, network switches, UPS units, and patch panels without stacking frames. That's enough vertical space to build a complete security or AV head-end in a single enclosure.
• 43-inch-wide 2-bay layout: The 41.5-inch overall width accommodates a side-by-side monitor-plus-rack arrangement. If your operations center design calls for an integrated workstation with a mounted display and active equipment in the same unit, this frame is sized for exactly that — no custom fab required.
• Monitor mounting support: Built-in monitor mounting capability means you can integrate display hardware directly into the frame rather than bolting a separate VESA arm to a wall or desk. For security consoles and AV operator stations, this keeps the footprint tight and the installation clean.
• 140 CFM rated airflow: The 140 CFM thermal rating matters when you're packing NVRs, amplifiers, or compute hardware into an enclosed furniture piece. Open-frame construction combined with this airflow spec means active electronics stay within thermal limits even under sustained load — important for 24/7 operations environments.
• 25.53-inch usable depth (64.9 cm): Full-depth rack gear fits without modification. Most 1U/2U security recorders and network appliances run 16–24 inches deep; the 25.53-inch usable depth clears that range with margin, so you're not shopping for shallow-mount variants of standard equipment.
• 10-32 rack rail threading: Standard 10-32 threaded rails are the rack hardware lingua franca for AV and security equipment. You won't need specialty cage nuts or adapter rails — any standard rack-mount gear drops straight in.
• TAA-compliant, USA-manufactured: Both Federal Ops Country of Origin (USA) and TAA compliance are confirmed for this SKU. If your project has Buy American, TAA, or GSA Schedule requirements, the L5-FLATFR-43LDW checks those boxes without a waiver or substitution conversation.
• No international availability: This model is domestic-only. If you're speccing a project with international shipping requirements, confirm availability at order time — do not assume cross-border fulfillment.

Integration & Compatibility

The L5-FLATFR-43LDW integrates into rack enclosure and technical furniture deployments where the frame serves as the structural backbone for a complete operator station or equipment bay. The 10-32 threaded rail system is compatible with standard EIA-310-compliant rack-mount equipment — servers, NVRs, UPS units, KVM switches, patch panels, and AV processors all mount without adapters.

Monitor mounting is built in, which pairs well with security workstation designs that co-locate display and recording hardware. For integrators building out a security operations center or AV control room, this frame eliminates the need for a separate monitor stand or wall-arm, reducing the total hardware BOM and simplifying the installation.

The 2-bay split is particularly useful when combining a network video recorder stack with operator displays — one bay holds the NVR and networking gear, the other accommodates the monitor, keeping signal and power cabling organized between compartments. For PoE network infrastructure feeding cameras back to this head-end, pair with an appropriate PoE switch racked within the same frame.

TAA compliance and USA origin make this a clean fit for federal, state, and local government projects operating under procurement rules that require domestic sourcing. No additional documentation is needed to assert TAA status on this SKU.

Frequently Asked Questions

Q: Is the L5-FLATFR-43LDW TAA compliant?

A: Yes. The L5-FLATFR-43LDW is confirmed TAA-compliant with a Federal Ops Country of Origin of USA. It is suitable for government and federally-funded projects with TAA or Buy American requirements.

Q: What rack rail thread standard does the L5-FLATFR-43LDW use?

A: The L5-FLATFR-43LDW uses standard 10-32 threaded rack rails, which are compatible with the vast majority of EIA-310 rack-mount equipment including NVRs, switches, UPS units, and AV processors. No cage nuts or adapter hardware required.

Q: How many rack units does the L5-FLATFR-43LDW provide?

A: The L5-FLATFR-43LDW provides 24 rack units (RU) of usable capacity within a 21-inch (53.3 cm) usable height.

Q: What is the usable depth of the L5-FLATFR-43LDW?

A: The usable depth is 25.53 inches (64.9 cm), which accommodates standard full-depth rack-mount equipment without modification.

Q: Does the L5-FLATFR-43LDW support monitor mounting?

A: Yes. The L5-FLATFR-43LDW includes integrated monitor mounting capability, allowing display hardware to be mounted directly within the frame — useful for security operations consoles and AV operator workstations.

Q: Is the L5-FLATFR-43LDW available for international shipment?

A: No. This model is listed as not available internationally. It is a domestic-only product. Confirm shipping destination requirements before ordering.

James Everett

The L5-FLATFR-43LDW is one of those frames I spec with confidence on government and municipal security projects precisely because it clears procurement without friction — TAA-compliant, USA-manufactured, and sized correctly for a real dual-bay operator console. The 24RU capacity inside a 41.5-inch-wide, 28.31-inch-deep chassis gives you enough room to build a complete head-end without stacking multiple enclosures.

Technical Highlights:

• 140 CFM airflow rating: Running NVRs and active network gear in enclosed technical furniture is a thermal problem waiting to happen if the frame isn't designed for it. The 140 CFM spec on this flat frame keeps equipment within operating limits on 24/7 security installations — important when you're recording from dozens of cameras continuously.
• 25.53-inch usable depth: This is the spec that trips up integrators who spec shallow. Standard 2U NVRs and managed PoE switches run 16–22 inches of chassis depth; 25.53 inches of usable depth means everything fits without sourcing short-depth variants at a cost premium.
• 10-32 threaded rails: Every rack-mount security and AV device you'll install uses 10-32 hardware. No cage nut trays, no rail adapters — just standard screws, which matters when you're commissioning on a tight schedule.

Deployment Considerations:

• At a shipping weight of 159 lbs (72.1 kg), plan your delivery and positioning crew accordingly — this is a two-person minimum lift before any equipment is installed. Factor floor load rating into the site survey for upper-floor or raised-access-floor deployments.
• Domestic-only availability means this frame cannot be ordered for international job sites. If a project has any cross-border component, confirm the shipping destination at quote stage, not at fulfillment.

The L5-FLATFR-43LDW is the right call for a fixed security operations console or AV control room where you need integrated monitor mounting, full-depth rack capacity, and confirmed TAA status — particularly on municipal, education, or federal work where sourcing documentation is reviewed at close-out.
