Middle Atlantic ERK-44-R-EXT3 Rack Front Extension Frame

The Middle Atlantic ERK-44-R-EXT3 Rack Front Extension Frame is a smart, scalable upgrade for 44U rack setups that need extra rear depth without a full cabinet replacement. Built with solid steel and finished in a sleek black, this extension frame provides a durable, space-maximizing solution for professionals who manage AV, IT, and audio-visual equipment. It is designed to be stacked for additional depth when your rack grows, and it accepts reuse of your existing doors for a seamless, cost-effective upgrade. With integrated electrical and cable pass-through knockouts, you gain cleaner cable management and safer, more organized power routing behind your equipment. If you’re looking to squeeze more performance from your current enclosure while preserving front-door access and the familiar door design, the ERK-44-R-EXT3 is the practical choice that blends reliability, versatility, and value.

• Adds 3" of usable depth to the rear of a 44U rack, expanding space for cables, power distribution, and rear-mounted accessories without sacrificing front-door access.
• 44U rack height compatibility in a sturdy steel frame with a black powder-coated finish, delivering a durable, professional look that withstands demanding install environments.
• Stackable design lets you add extra depth when needed, enabling scalable configurations as equipment and cable runs grow over time.
• Compatible with existing doors—these doors can be reused, reducing upgrade costs and preserving your current aesthetic and mounting layout.
• Includes electrical and cable pass-through knockouts, simplifying power and data routing while helping you maintain tidy, compliant cable management behind the rack.

How to install Middle Atlantic ERK-44-R-EXT3

• Begin by verifying your current rack is a 44U setup and that you are prepared to extend the rear depth. Confirm you have access to the rear of the enclosure and that the doors you plan to reuse are compatible with the extension frame mounting points.
• Position the ERK-44-R-EXT3 extension frame at the rear of the existing rack and align the mounting holes with the rack’s vertical rails. The frame is designed to integrate with standard mounting features of compatible ERK series racks.
• Secure the extension frame to the rack using the appropriate mounting hardware (as supplied or specified by your rack system). Ensure all fasteners are tightened to provide a stable, vibration-resistant installation that won’t loosen under typical use.
• Route power and data cables through the built-in electrical and cable pass-through knockouts. Plan your cable paths to maximize airflow and minimize bend radii, keeping front-to-back cable management clean and compliant with safety standards.
• If you are adding more than one extension or reusing multiple doors, stack additional ERK-44-R-EXT3 frames as needed and align them carefully. After mounting, reattach the original door panels and test door clearance to ensure full operation without interference.
