Middle Atlantic 1in. Space Decorative Panel Mounts Four Low-Voltage Decora Devices Steel - DECP-1X4

Middle Atlantic DECP-1X4 1RU Four-Port Decorative Decora Device Panel

Overview

The Middle Atlantic DECP-1X4 is a 1-rack-unit steel panel that punches out four Decora-style knockouts across a standard 19-inch rack opening — giving integrators a clean, finished way to bring low-voltage AV, control, and security devices directly into an equipment rack or enclosure. If you've ever had a client ask why a keypad, button station, or IR receiver is zip-tied to the side of a rack instead of mounted flush in a blank panel, this is the part that fixes it. The DECP-1X4 (often searched as DECP 1X4) ships in black powder coat over steel, matching Middle Atlantic rack and enclosure finishes out of the box.

At only 0.52 inches deep and 1.75 inches tall, the panel adds negligible depth penalty in shallow enclosures and disappears behind the rack rail when viewed from the front — a detail that matters on open-frame racks in finished AV rooms or security operations centers where appearance is part of the deliverable.

Key Features

• Four Decora Knockouts in 1 RU: Four side-by-side openings sized for standard Decora low-voltage devices — enough to terminate a small conference room's worth of control interfaces (volume, source, intercom call button, IR blaster) in a single rack unit. Consolidating these into the rack instead of scatter-mounting them to walls keeps cable runs short and service calls simple.
• 19-Inch Standard Rack Width: Fits EIA-standard 19-inch racks and enclosures without modification. Compatible with Middle Atlantic racks and virtually any third-party EIA rack — no adapter hardware required.
• 1 RU Height (1.75 inches): One rack unit is the tightest standard increment. Placing four device openings in 1 RU means you're not burning 2 or 3 U on a handful of low-voltage interfaces. In a densely loaded rack, that saved space matters.
• 0.52-Inch Depth: The panel adds just over half an inch of protrusion behind the mounting surface. In shallow-depth wall-mount enclosures where rear clearance is limited, this low-profile dimension keeps the panel from conflicting with cable management or rear-mounted equipment.
• Steel Construction with Black Powder Coat Finish: Steel over a comparable plastic blank means the panel holds its shape when devices are pressed into the knockouts repeatedly over time. The black powder coat matches standard Middle Atlantic rack finishes, so the installed result looks intentional rather than assembled from mismatched parts.
• Lightweight at 0.6 lbs Shipping Weight: Easy single-technician installation with no special tooling or handling. The low mass also means no rack balance concerns when installed in an upper rack position.

Integration & Compatibility

The DECP-1X4 is designed for standard Decora low-voltage device inserts — the same form factor used across a wide range of control, AV, and security interfaces from manufacturers including Legrand, Leviton, Crestron, AMX, and others. It mounts in any rack accessory slot on a 19-inch EIA-standard rack or enclosure, including Middle Atlantic's own Middle Atlantic rack and enclosure line.

Common deployment pairings include in-rack button stations for AV system control, IR repeater emitters and receivers, volume control interfaces, intercom call buttons, and low-voltage data keystone inserts where a full keystone patch panel is more than the job requires. If you're specifying an AV rack or equipment enclosure build-out and need to surface a handful of Decora devices without custom fabrication, the DECP-1X4 is the correct off-the-shelf answer.

For larger device counts or mixed Decora/keystone configurations, Middle Atlantic offers additional panel variants in the DECP family — evaluate the total device count and knockout layout required before ordering multiples of this SKU versus a higher-capacity panel in the same series.

Frequently Asked Questions

Q: How many Decora device positions does the DECP-1X4 provide?

A: The DECP-1X4 provides four Decora-style knockouts in a single 1 RU panel, accommodating up to four low-voltage Decora devices side by side.

Q: What rack width does the DECP-1X4 fit?

A: The panel is 19 inches wide and fits standard EIA 19-inch racks and enclosures.

Q: How deep is the DECP-1X4? Will it fit in a shallow wall-mount enclosure?

A: The panel is 0.52 inches (1.3 cm) deep — a very low-profile dimension that works well in shallow enclosures with limited rear clearance.

Q: What finish does the DECP-1X4 come in?

A: The DECP-1X4 is finished in black powder coat over steel, matching standard Middle Atlantic rack and enclosure aesthetics.

Q: What types of devices can be installed in the DECP-1X4 knockouts?

A: Any standard Decora low-voltage device insert fits — including AV control interfaces, IR repeaters, volume controls, intercom buttons, and similar form-factor devices from major AV and security manufacturers.

Q: Does the DECP-1X4 require any special mounting hardware?

A: The panel is a standard 19-inch 1 RU rack-mount panel and installs using standard rack screws into an EIA-rack's mounting rails. No special adapter hardware is required.

The DECP-1X4's value proposition is straightforward: four Decora openings in 1.75 inches of rack height. What that actually means on a job is the difference between a rack that looks finished and one that looks like an afterthought. I reach for this panel on any project where Decora-format control or AV interfaces need to land inside a rack or enclosure rather than on a nearby wall — and the 0.52-inch depth means I've never had a clearance conflict, even in 12-inch-deep wall-mount boxes.

Technical Highlights:

• Four Knockouts, 1 RU: At 1.75 inches tall across a 19-inch width, you're getting four device positions without burning multiple rack units — efficient on any rack with a tight U-count.
• 0.52-Inch Depth: Genuinely shallow. In a wall enclosure where rear-to-door clearance might only be 3–4 inches, this panel won't compete for space with cabling or rear-mount gear.
• Steel + Powder Coat: The panel holds knockout integrity under repeated device insertions — a detail you notice after the third service call when a plastic blank would have started to flex or crack at the cutout edges.

Deployment Considerations:

• Confirm your Decora device inserts are low-voltage form factor before ordering — standard Decora electrical devices use a different gang-box mounting system and are not designed for rack-panel installation.
• At 0.6 lbs shipping weight, the panel itself is light, but factor in the weight of four installed Decora devices when assessing rack balance, particularly in top-heavy open-frame racks.

Best fit for a conference room AV rack or a security operations console where a handful of Crestron, AMX, or Legrand Decora control interfaces need to surface cleanly inside the rack rather than being field-fabricated into a blank panel — the DECP-1X4 is the pre-made answer to that specific problem.
