Middle Atlantic RL Series Relay Rack (84IN. Height) Black Finish - RL10-45

Middle Atlantic RL10-45 45U 2-Post Open Frame Relay Rack

The Middle Atlantic RL10-45 is a 45U, 2-post open-frame steel relay rack built for AV, security, and IT infrastructure deployments where access, airflow, and load capacity matter more than enclosure aesthetics. At 84.62 inches tall with 78.75 inches of usable rack height, the RL10-45 (often searched as RL10 45) provides a full 45U of 10-32 threaded rail space — enough vertical real estate to rack out a complete NVR stack, UPS, patch panels, and KVM without compromise. TAA-compliant and manufactured in the USA, this rack suits federal, government, and public sector installations where country-of-origin documentation is required.

Key Features

• 45U / 78.75 in Usable Height: A full 45 rack units gives you room to grow. Deploy NVRs, encoders, network switches, and power distribution in a single vertical column without overflow — unlike 42U racks that force you to split systems across two units.
• 1,600-lb Weight Capacity: At 725.7 kg rated capacity, this rack handles dense equipment loads — multi-drive NVR servers, battery-backed UPS units, high-density patch fields — without structural concerns. The 400-lb UL-listed load capacity provides a conservative certified benchmark for compliance-sensitive environments.
• 10-32 Threaded Rails: Industry-standard 10-32 tapped rail holes are compatible with virtually every commercial rack-mount component shipping today. No cage nuts required — install equipment faster and eliminate the stripped-cage-nut problem common on older 12-24 rails.
• Open-Frame 2-Post Design: The open frame gives unrestricted rear access for cable dressing, power wiring, and equipment swaps without pulling the unit away from the wall. Ideal for equipment rooms where technicians need to work both sides simultaneously during commissioning or maintenance windows.
• 15.25-in Total Depth / 3-in Usable Depth: The shallow 15.25-inch footprint (38.7 cm) lets the rack fit in tight mechanical rooms, closets, or against walls where a 4-post enclosed cabinet simply won't fit. The 3-inch usable depth behind the rail accommodates standard rack ears — note that deep chassis requiring rear-rail support will need a 4-post solution instead.
• 84.62-in Height with Black Finish: The full-height 214.9 cm profile maximizes density in standard ceiling-height equipment rooms. The black powder-coat finish reduces glare in low-light server rooms and matches most commercial AV and security equipment aesthetics.
• 40-lb Shipping Weight: At 18.1 kg, a single technician can receive and position this rack without a lift or additional labor — a meaningful factor when you're commissioning multiple racks in a building or retrofitting an existing room.
• TAA Compliant / UL Listed / USA-Made: TAA compliance covers federal procurement requirements. UL listing covers the rack's structural and load ratings for insurance and facilities documentation. Country of origin is USA — verifiable for GSA schedule and Buy American Act requirements.

Integration and Compatibility

The RL10-45 accepts standard 19-inch rack-mount equipment on 10-32 threaded rails. It is compatible with network video recorders, managed PoE switches, patch panels, KVM units, and rackmount UPS systems from virtually any manufacturer. For security integrators building out surveillance systems, this rack pairs cleanly with multi-channel NVRs, encoder banks, and the supporting network infrastructure in a single vertical footprint. Integrators sourcing from the broader Middle Atlantic rack and enclosure line will find accessories — rack shelves, cable managers, mounting brackets, and PDUs — designed to fit this frame directly. For deployments requiring enclosed protection or additional cable management, review rack cabinet options as an alternative. If your equipment requires rear-rail support (deep servers, blade chassis), this 2-post open-frame design is not the right choice — a 4-post configuration is required.

Frequently Asked Questions

Q: Is the Middle Atlantic RL10-45 TAA compliant?

A: Yes. The RL10-45 is TAA compliant and manufactured in the USA, making it suitable for federal, state, and government procurement under Buy American Act and GSA schedule requirements.

Q: What rail type does the RL10-45 use — do I need cage nuts?

A: The RL10-45 uses 10-32 threaded (tapped) rails. No cage nuts are required. Standard 10-32 screws used by virtually all commercial rack-mount equipment work directly.

Q: What is the maximum load capacity of the RL10-45?

A: The RL10-45 has a 1,600-lb (725.7 kg) total weight capacity and a UL-listed load capacity of 400 lbs (181.4 kg). The UL figure is the certified benchmark for compliance documentation; the 1,600-lb figure represents the structural rating of the frame.

Q: Will deep rack-mount servers fit in the RL10-45?

A: The RL10-45 is a 2-post open-frame rack with 3 inches of usable depth behind the rail. It supports standard rack-mount equipment that mounts to front rails only. Deep chassis — 2U servers, blade systems, or any equipment requiring rear-rail support — need a 4-post rack configuration.

Q: How many rack units does the RL10-45 provide?

A: The RL10-45 provides 45U of rack space with 78.75 inches (200 cm) of usable height. Overall frame height is 84.62 inches (214.9 cm).

Q: Is the RL10-45 suitable for a security equipment room with limited floor space?

A: Yes. At 15.25 inches deep and 19.62 inches wide, the RL10-45 has a compact footprint that fits in tight equipment closets, IDF rooms, and wall-adjacent installations where a full-depth enclosed cabinet would not clear the space. The open-frame design also preserves rear access without requiring the rack to be pulled away from the wall.

The RL10-45's 1,600-lb structural capacity is the spec I keep coming back to on larger security deployments. When you're stacking multiple multi-drive NVRs, a rackmount UPS, and a dense PoE switch shelf in a single 45U frame, weight adds up fast — and the RL10-45 is built to absorb that load without question. This is a rack you populate once and don't worry about again.

Technical Highlights:

• 45U / 78.75 in Usable Height: Full 45 units of vertical space in a single 84.62-inch frame. In a typical security head-end, that covers a 64-channel NVR, a managed PoE switch, a KVM, a patch panel, and a UPS with room to add recorders as camera counts scale.
• 10-32 Threaded Rails: Tapped rails accept standard 10-32 screws directly — no cage nut installation, no stripped hardware on the third swap. Every commercial NVR, switch, and PDU on the market ships with 10-32 rack hardware, so compatibility is a non-issue.
• TAA Compliant / USA-Made: Country of origin documentation is USA. For government end users, integrators running GSA schedules, or school district deployments subject to Buy American requirements, this is a procurement prerequisite — not a marketing point.

Deployment Considerations:

• The 3-inch usable depth behind the front rail is the hard constraint here. Patch panels, 1U switches, and NVR front-mount chassis are fine. Any equipment requiring rear-rail support — deep 2U servers, blade enclosures — cannot be used with this 2-post configuration. Spec the equipment load before committing to this rack form factor.
• At 15.25 inches total depth and 19.62 inches wide, the footprint is compact enough for IDF closets, but the 84.62-inch height means ceiling clearance needs to be confirmed before delivery — especially in retrofit installations with drop ceilings or low mechanical soffits.

The RL10-45 is the right call for security integrators building out NVR head-ends in government facilities, school districts, or municipal buildings where TAA compliance is a hard bid requirement and the equipment mix is front-mount-only rack gear. For mixed deep-server environments, move to a 4-post solution.
