A practical, dependable solution for integrating DIN rail equipment into standard rack systems backed by Hammond quality and Area51 expertise.

If you work with DIN rail-mounted equipment, relays, terminal blocks, PLCs, power supplies, or automation modules, you already know the challenge: how do you cleanly integrate these components into a standard 19-inch rack environment? Mismatched mounting systems lead to messy wiring, wasted space, and headaches down the line.

Hammond Manufacturing has solved this with the RMAD Series Adjustable Rack Mount DIN Rail Kit. It’s one of those products that makes you wonder why you ever did it any other way. And here at Area51 Electronics, it’s one of our go-to recommendations for customers building hybrid IT/OT rack environments.

What Is the RMAD Series?

The RMAD Series is a 2U steel panel kit that mounts directly to standard EIA-310 19-inch rack rails, instantly converting that rack space into a fully functional DIN rail mounting platform. It ships with a 0.3-inch thick top-hat DIN rail (DIN 3 profile) already included, so you can start snapping in equipment right away.

The adjustable depth, up to 8.38 inches, means you can properly position components inside the rack without compromise. Cable pass-through cutouts on both the rear and sides keep wiring tidy and organized. The result is a clean, professional installation that holds up in the field.

RMAD vs. RMHD: Which One Do You Need?

Hammond offers two versions of this kit, the light-duty RMAD and the heavy-duty RMHD. Both products solve the same problem. The primary difference is load capacity.  Here’s a quick side-by-side so you can choose the right fit for your application:

For most DIN rail applications, terminal blocks, relays, smaller PLCs, and communication modules, the RMAD’s 26 lb rating is more than sufficient. If you’re mounting heavier industrial components or need maximum robustness, step up to the RMHD. Not sure which one fits your project? Give our team a call, we’re happy to help you spec it out.

Where Does the RMAD Series Shine?

The RMAD Series is purpose-built for environments where DIN rail and rack infrastructure need to coexist. Common applications include:

•   Industrial control panels integrated into IT rack systems
•   Telecom and network installations with mixed equipment types
•   Data centers running hybrid IT/OT environments
•   Power supplies, relay modules, and automation devices in rack form
•   Wall-mount and floor-standing rack systems in manufacturing or utilities

Essentially, if you’ve ever found yourself asking, “How do I get these DIN rail components into this rack?” the RMAD is your answer.
