Middle Atlantic 12 Pc. U1 Rackshelf Pack in Self-merchandising Display BOX - U1-RP12

Middle Atlantic U1-RP12 1U Utility Rack Shelf — 12-Pack

Overview

The Middle Atlantic U1-RP12 is a 1U universal rack shelf designed for integrators and rack builders who need a reliable, no-frills platform for mounting non-rack-native equipment. At 19 inches wide and 10.78 inches deep with a 35 lb weight capacity, it handles the majority of AV components, power strips, small switches, and ancillary gear that doesn't ship with its own rack ears. This listing is a 12-piece merchandising pack — meaning you get a full dozen shelves in a single order, which makes it the practical choice for multi-rack deployments or stocking your van for a project run.

The U1-RP12 (often searched as U1 RP12) is sourced factory-new from Middle Atlantic, a Legrand AV brand with a long track record in rack accessories and structured enclosure systems.

Key Features

• 1U form factor, 19" rack width: Fits any standard EIA 19-inch equipment rack without modification. One rack unit of vertical space consumed — keeps your panel density high when you're stacking multiple components.
• 35 lb weight capacity: Enough to carry a compact NVR, a small UPS, a media converter shelf, or a bundle of power conditioning gear. Know your load before you rack it — 35 lbs is the ceiling, not the target.
• 10.72" usable depth: The shelf's usable interior runs 10.72 inches (27.2 cm), which accommodates most shallow-depth equipment. Measure your component's depth before ordering — deep 1U appliances can exceed this.
• 10.78" overall depth: The total shelf footprint is 10.78 inches, giving you a clear picture of how it sits relative to your rack's front-to-back clearance and cable management pathway.
• Solid (non-vented) deck: The shelf surface is unperforated. This is intentional for equipment that doesn't require active airflow from below — small peripherals, passive converters, labeled patch panels. If your component needs bottom ventilation, pair it with a vented shelf variant instead.
• 2 mounting points: Mounts via two standard rack ear attachment points. Quick to install, consistent with standard rack rail spacing. No cage nuts or specialty hardware required beyond what ships with your rack.
• 12-unit pack: The RP12 suffix signals the pack quantity — twelve shelves per box. For integrators building out multiple racks on a single job, ordering by the pack eliminates per-unit reorder friction and typically improves per-shelf cost.
• 1.75" height (standard 1U): Precise 1U height of 1.75 inches ensures clean rack unit accounting. Stack these without dead space between other rack-mounted devices.

Integration & Compatibility

The U1-RP12 installs into any EIA-standard 19-inch rack rail system — open-frame, enclosed cabinet, or wall-mount rack with adequate depth. At 10.78 inches total depth, verify your rack's usable front-to-back dimension before ordering, particularly in shallow-depth wall enclosures where clearance is tight. The shelf is compatible with standard rack screws (10-32 or M6 depending on your rail type) — confirm your rack's threading before installation.

Commonly deployed alongside network video recorders, PoE injectors, media converters, and small form-factor appliances in security and AV rack builds. For integrators specifying full rack systems, pair with Middle Atlantic's rack power management products for a cohesive enclosure build. A rack planning guide can help you map unit counts and cable routes before equipment arrives on site.

Frequently Asked Questions

Q: How many shelves are included in the U1-RP12 pack?

A: The U1-RP12 is a 12-piece pack — you receive 12 individual 1U rack shelves in a single self-merchandising display box.

Q: What is the weight capacity of each shelf?

A: Each shelf supports up to 35 lbs (15.9 kg). Size your load accordingly — this covers most small AV components and network appliances, but verify before racking heavier equipment.

Q: Will this shelf fit my existing rack?

A: The U1-RP12 is 19 inches wide and designed for standard EIA 19-inch rack rails. It occupies 1U (1.75 inches) of vertical space. Confirm your rack's rail threading (10-32 or M6) and that you have at least 10.78 inches of usable depth available.

Q: Is the shelf surface vented?

A: No — the U1-RP12 deck is solid and non-vented. Use it for equipment that does not require bottom airflow. For gear that needs ventilation from below, select a vented shelf variant.

Q: What is the usable depth of the shelf?

A: The usable interior depth is 10.72 inches (27.2 cm). The total shelf depth including the mounting lip is 10.78 inches (27.4 cm). Measure your equipment's footprint against 10.72 inches to confirm fit.

Q: Is the U1-RP12 appropriate for camera or NVR installations?

A: Yes — it is frequently used to shelf-mount compact NVRs, media converters, and other non-rack-native security components. The 35 lb capacity handles most 1U-class NVRs and small appliances without issue.

Ted Perry

The Middle Atlantic U1-RP12 comes up constantly on multi-rack security installs — specifically because most NVR vendors and small appliance makers still don't ship rack ears, and you need a consistent, in-stock solution that doesn't vary between jobs. The 35 lb weight capacity and 10.72-inch usable depth cover the vast majority of 1U security appliances I've racked, and getting 12 units per box means I'm not placing individual shelf orders mid-project.

Technical Highlights:

• 35 lb capacity: Handles compact NVRs, PoE injectors, and small switches without issue. Know that 35 lbs is a hard ceiling — for heavier multi-bay recorders or UPS units, you'll need a heavier-rated shelf.
• 10.72" usable depth: Fits most shallow-to-mid depth 1U appliances cleanly. Anything deeper than 10.72 inches will overhang — measure first, especially in enclosed cabinets where the rear cable channel matters.
• Solid (non-vented) surface: The unperforated deck is the right call for passive or low-heat gear. Don't shelf-mount a 1U device with bottom intake vents on this shelf — you'll starve it of airflow.

Deployment Considerations:

• The 12-pack format is only practical if you actually need multiples — on a single-rack job, individual shelf SKUs may be more economical. The RP12 pack is the right buy for stocking a project van or equipping a multi-rack IDF/MDF build.
• Confirm rail threading before the truck rolls — 10-32 and M6 are not interchangeable, and a shelf delivered to a site with mismatched rail hardware creates a real delay.

The U1-RP12 12-pack is the right specification for systems integrators running parallel rack builds — security operations centers, multi-IDF campus deployments, or warehouse surveillance buildouts where rack count is in double digits and consistency across enclosures matters.
