Middle Atlantic RL Series 45RU 2-Post Open Frame Rack

The RL12-45 2-post open frame rack from Middle Atlantic’s RL Series is engineered for reliability, flexibility, and rapid installation in data centers, broadcast studios, server rooms, and AV installations. Built to handle demanding equipment loads, this open-frame solution combines industrial-strength steel with precision engineering to deliver a sturdy mounting platform that stays square and level even under heavy equipment. Its streamlined design makes it easy to assemble, while its open frame construction provides excellent airflow and effortless access for maintenance, cable runs, and future upgrades. Whether you’re mounting network switches, servers, audio/visual gear, or a mix of equipment, the RL12-45 brings together durability, ease of use, and professional-grade performance in a compact footprint.

• Self-squaring and self-leveling design — The RL12-45 features a self-squaring, self-leveling frame that helps you achieve accurate alignment without painstaking adjustments. This design ensures the cabinet sits perfectly plumb and level, improving mounting precision and reducing installation time.
• 25/45U open-frame versatility — With a generous 45U capacity, this 2-post open frame rack accommodates a wide range of equipment, from compact servers to larger switches and AV gear. The open-frame format offers flexible mounting options and easy access for front and rear cable management.
• Robust, durable construction — Built from heavy-duty steel with a durable finish, the RL12-45 is designed to withstand the rigors of professional environments. Its strong chassis supports equipment weight with long-term stability, while resistive finishes protect against corrosion and wear in busy data rooms and studios.
• Efficient cooling and airflow — The open-frame design promotes superior airflow around mounted equipment, helping maintain optimal temperatures and reduce the risk of thermal throttling. This improves reliability for high-density deployments and equipment with substantial heat output.
• Easy assembly and serviceability — Quick-start hardware and clearly aligned channels make assembly straightforward, even for deployments with tight timelines. The design also simplifies maintenance and upgrades, enabling rapid access to components without sacrificing structural integrity.

How to install Middle Atlantic RL Series 45RU 2-Post Open Frame Rack

• Unpack the RL12-45 and verify all components against the hardware list. Ensure you have the mounting rails, screws, and any required leveling or stabilizing accessories.
• Prepare your installation location. Clear the area, confirm a level floor, and ensure there is adequate ventilation for airflow around the rack. If mounting near walls or corners, plan cable routing to minimize obstruction.
• Assemble the frame using the self-squaring and self-leveling design. Align the posts, fasten chassis components, and confirm the frame sits plumb and level. Tighten connections to specification, but avoid over-tightening to prevent distortion.
• Install 19-inch mounting rails and attach them securely to the rails where your equipment will mount. Use appropriate cage nuts and screws for your devices, ensuring each piece is firmly anchored to prevent movement during operation or transport.
• Mount equipment starting from the bottom to optimize weight distribution. Route cables efficiently with clean trunking or tie-downs, leaving space for cable slack and future expansion. Close any front and rear channels as needed and perform a final check for level, stability, and airflow clearances.

Frequently asked questions

• What is the capacity of the RL12-45 2-Post Open Frame Rack?
