Middle Atlantic 12PC. PHBL-1 Contract PAC - PHBL1-CP12

Middle Atlantic PHBL1-CP12 1U Flat Blank Panel Contractor Pack — 12 Pieces

Overview

The Middle Atlantic PHBL1-CP12 is a contractor pack of twelve 1U flat blank panels — the practical answer to open rack slots that compromise airflow management, expose live equipment to accidental contact, and leave a rack looking unfinished on a client walkthrough. Each panel is 19 inches wide and 1.8 inches tall, machined from aluminum and finished in flat black powder coat that matches standard Middle Atlantic rack enclosures without standing out. If you're outfitting a new rack build or backfilling open slots in an existing install, buying the PHBL1-CP12 as a 12-piece contractor pack beats sourcing individual panels every time — you'll use them.

Blank panels are one of those line items that disappear from project BOMs until the integrator is standing in front of a half-populated rack wondering why the UPS is running warm. These aren't decorative. Proper slot coverage forces airflow through equipment rather than around it, keeps fingers and tools away from energized backplanes, and satisfies the install standards most enterprise and government clients enforce during site acceptance. The Middle Atlantic rack accessories lineup covers everything from blanks to cable management — this pack fits cleanly into that broader system.

Key Features

• 12-Piece Contractor Pack: Twelve panels per order means you have enough to fill a freshly built 24U rack to roughly 50% blank coverage without a second purchase order. For integrators running multiple installs, one pack per job keeps the truck stocked.
• 1U Form Factor (1.8" height, 19" width): Designed for standard 19-inch EIA racks. Each panel occupies exactly one rack unit — no cutting, no shimming. The 1.8-inch height leaves no gap above or below mounted equipment in a properly assembled rack.
• Aluminum Construction: Aluminum panels are rigid enough to stay flat across the full 19-inch span without bowing — a real issue with cheap steel alternatives that warp under their own weight and leave visible gaps. Aluminum also stays light: the full 12-pack weighs 6.35 lbs total, so shipping cost is negligible and the panels don't add meaningful load to the rack.
• Flat Black Powder Coat Finish: The flat (non-glossy) powder coat finish resists fingerprints and scuffs better than painted or anodized surfaces, and it matches the interior of Middle Atlantic enclosures without the sheen mismatch you get with brushed or polished alternatives. Clients notice. Inspectors notice.
• Solid, Flat Panel Design: No vents, no cutouts. A solid panel provides complete EMI shielding on the slot and prevents tool-tip contact with adjacent equipment. If you need vented blanks for specific airflow configurations, that's a different SKU — but for standard blanks in a managed airflow rack, solid is correct.
• Compatible with Standard 19" EIA Racks: These panels are not Middle Atlantic enclosure-exclusive. Any rack built to the 19-inch EIA/IEC standard — third-party open frames, enclosed cabinets, wall-mount racks — will accept them. Useful when you're mixing enclosure brands on a site.

Integration & Compatibility

The PHBL1-CP12 panels are dimensionally standard: 19-inch width, 1U (1.8-inch) height. They install into any rack that conforms to EIA-310 / IEC 60297 19-inch rack standards. No tools beyond a standard screwdriver are required; rack nuts and screws are not included in this pack (source separately if your rack uses cage nuts rather than pre-tapped strips). These panels are a natural complement to a broader rack accessories build-out that includes cable management, patch panels, and power distribution. For integrators working primarily in security rack systems, they pair with NVR shelves, managed PoE switches, and network equipment without any fitment concerns.

If your project includes a mix of 1U, 2U, and 3U gaps, note that this pack covers only 1U slots. Multi-unit blank panels are separate SKUs in the Middle Atlantic line. Plan your open-slot count before ordering to confirm this pack covers your full requirement — a 12-rack deployment with two open slots per rack will exhaust this pack exactly, with nothing left for adds or repairs.

Frequently Asked Questions

Q: What rack standard do the PHBL1-CP12 panels fit?

A: These are standard 19-inch EIA/IEC rack blank panels — 19 inches wide and 1U (1.8 inches) tall. They fit any rack built to EIA-310 or IEC 60297 19-inch standards, including open-frame, enclosed cabinet, and wall-mount rack enclosures from any manufacturer.

Q: Do the PHBL1-CP12 panels include mounting hardware?

A: The pack includes 12 aluminum blank panels. Mounting hardware (cage nuts, rack screws) is not listed as included in the package contents. Source rack screws or cage nuts separately based on your rack's rail type.

Q: How many panels are in the PHBL1-CP12 contractor pack?

A: The PHBL1-CP12 contains exactly 12 panels — one contractor pack of twelve 1U flat blank panels. The total pack weight is 6.35 lbs.

Q: Are these panels vented or solid?

A: Solid. The PHBL1-CP12 panels are flat and solid with no perforations or vents. This makes them correct for standard blank-slot coverage where you want complete EMI shielding and no accidental tool or finger contact with adjacent equipment. If your airflow configuration requires vented blanks, that is a different SKU.

Q: Can the PHBL1-CP12 (often searched as PHBL1 CP12) be used in non-Middle Atlantic racks?

A: Yes. These panels conform to standard 19-inch EIA rack dimensions and are not exclusive to Middle Atlantic enclosures. They will fit any third-party rack that meets the 19-inch EIA-310 standard.

Q: What is the material and finish on these blank panels?

A: The panels are machined from aluminum and finished in flat black powder coat. The flat finish resists fingerprinting and scuffing and matches standard Middle Atlantic rack enclosure interiors.
