Middle Atlantic 12 Piece PBL-1 Contractor Pack Flanged Aluminum Panels in Poly Bags - PBL1-CP12

Middle Atlantic PBL1-CP12 1RU Flanged Aluminum Blank Panel Contractor Pack

Overview

The Middle Atlantic PBL1-CP12 is a contractor pack of 12 flanged aluminum blank panels, each occupying exactly 1 RU (1.75 in) in a standard 19-inch equipment rack. If you're commissioning a new rack build, closing out an AV or security rack, or stocking a service van for installs, this pack gives you a dozen panels in a single SKU — enough to button up most mid-size builds without placing multiple orders. Each panel ships individually wrapped in a poly bag, keeping them scratch-free until you're ready to drop them in.

The PBL1-CP12 (often searched as PBL1 CP12) is designed to close open rack slots that would otherwise compromise airflow management, expose equipment to dust ingress, and create visible gaps in finished installations. These are the panels you reach for when the rack is done and you need to fill the blanks before the customer walkthrough.

Key Features

• 1 RU Form Factor (1.75 in tall): Each panel fills exactly one rack unit — the standard denominator in equipment racks. No cutting, no shimming. Drop it in, screw it down, move to the next slot.
• Flanged Aluminum Construction: The flanged design gives each panel structural rigidity without adding meaningful weight. Aluminum keeps the pack light enough for a service bag while still providing a finished, professional appearance that holds flush against the rack rails.
• Black Powder Coat Finish: Powder coat is more durable than paint — it resists chipping and scratching during repeated installs and rack reconfigurations. The black finish matches the interior of most commercial rack enclosures.
• Standard 19-Inch Width: At exactly 19 in wide, these panels fit any EIA-standard equipment rack — security head-end racks, AV racks, IT server cabinets, and network enclosures — without modification.
• 0.52 in Depth: The shallow 0.52 in depth means these panels won't intrude on cable management space behind the panel face. In tight wall-mount enclosures or shallow racks where depth is a premium, that matters.
• Ideal for Machining: The aluminum stock is noted as suitable for field machining — if an install requires a custom cutout for a cable passthrough or a panel-mount connector, these can be drilled or punched without cracking or delaminating like thin steel panels sometimes do.
• 12-Piece Contractor Pack: Buying 12 at once drops your per-unit cost and eliminates the friction of reordering mid-job. One SKU covers a full rack's worth of blanks for most security and AV installs.
• Individual Poly Bag Packaging: Each panel arrives in its own poly bag — practical for job-site storage and for handing panels off to a helper without risking scratches on finished surfaces.

Integration & Compatibility

The PBL1-CP12 panels are compatible with any EIA-standard 19-inch rack using standard rack screws. They are not keyed to Middle Atlantic enclosures specifically — use them in any brand of open-frame rack, wall-mount enclosure, or free-standing cabinet that follows the 19-inch EIA rack standard. The flanged edges align to standard rack rail hole patterns (both square-hole and round-hole rails, using the appropriate hardware).

Common deployment contexts include: security and access control head-end racks, NVR/DVR enclosures, AV distribution racks, and IT patch/switching cabinets where empty rack units need to be covered for airflow and dust control. Pair these with a rack accessories order that includes cable management panels or brush strips if you're doing a full rack buildout.

Middle Atlantic produces a broad line of Middle Atlantic rack infrastructure — these blank panels are the finishing hardware that completes any installation from their enclosure or open-frame rack lineup.

Frequently Asked Questions

Q: How many rack units does each panel in the PBL1-CP12 pack cover?

A: Each panel covers exactly 1 RU (1.75 inches tall). The PBL1-CP12 pack contains 12 individual panels, so the pack covers up to 12 rack units total.

Q: Will the PBL1-CP12 panels fit racks from other manufacturers, or only Middle Atlantic enclosures?

A: These panels fit any EIA-standard 19-inch rack regardless of brand. The 19-inch width and flanged design are compatible with standard rack rail hole patterns across open-frame racks, wall-mount enclosures, and free-standing cabinets.

Q: What material and finish are the PBL1-CP12 panels?

A: The panels are constructed from aluminum with a black powder coat finish. Powder coat is more chip-resistant than standard paint, which helps them hold up during repeated rack reconfigurations.

Q: Can the PBL1-CP12 panels be drilled or modified in the field?

A: Yes. The aluminum construction is noted as ideal for machining, so field drilling or punching for cable passthroughs or panel-mount connectors is feasible without cracking or delaminating the panel.

Q: How are the panels packaged — can I pull individual panels without handling the whole pack?

A: Yes. Each of the 12 panels ships individually wrapped in its own poly bag, so you can pull single panels without exposing the rest to scratches or contamination on a job site.

Q: What rack screw type is required for the PBL1-CP12?

A: The panels use standard rack hardware consistent with EIA 19-inch racks. Specific screw type (M6, 10-32, or 12-24) depends on your rack rail — the panels themselves accept standard rack screws; no proprietary fasteners are required.

The PBL1-CP12 is the kind of SKU that experienced integrators keep on standing order — 12 flanged aluminum panels at 1RU each, 0.52 in deep, black powder coat, individually bagged. Nothing glamorous about it, but an uncovered rack slot is a dust path and an airflow bypass, and on a finished security head-end installation it looks unfinished. Having a dozen of these on hand when you close out a rack is just standard practice.

Technical Highlights:

• Flanged Aluminum at 0.52 in Depth: The flange gives you structural rigidity without the depth penalty — 0.52 in means these won't eat into cable management space in shallow wall-mount enclosures where every inch behind the panel face counts.
• Black Powder Coat Finish: More durable than spray paint or anodizing for this application — powder coat holds up to the repeated installs and rack reconfigs that a contractor pack implies. No flaking onto equipment below.
• 12-Piece Contractor Pack: One SKU, 12 panels, individually poly-bagged. Enough to finish most 2U–42U builds without a reorder mid-job. The per-unit economics of buying a pack vs. singles are straightforward.

Deployment Considerations:

• The aluminum stock is listed as suitable for machining — if a run requires a cable passthrough or a panel-mount USB port, you can drill or punch these without the cracking risk you sometimes get with thinner stamped steel panels.
• These panels are 19 in wide and fit standard EIA racks, but confirm your rail hole type (square, round, or threaded) before ordering rack screws separately — the panels don't include mounting hardware, and screw type varies by rail.

The PBL1-CP12 is the right buy for integrators running multiple security or AV rack installations per month — stock a box in the service van, close out every open slot on every job, and stop treating blank panels as an afterthought reorder.
