Middle Atlantic SB1 Contractor Pack Textured Flanged Blank Panels in Plain Poly Bags 12 - SB1-CP12

Middle Atlantic SB1-CP12 1U Flanged Blank Rack Panels — 12-Piece Contractor Pack

Overview

The Middle Atlantic SB1-CP12 delivers exactly what rack integrators burn through on every multi-bay deployment: a 12-piece contractor pack of 1U flanged steel blank panels, shipped in plain poly bags and ready to drop into any standard 19-inch rack. Each panel ships in textured black powder coat, matches the finish of Middle Atlantic rack enclosures and most third-party frames, and installs in seconds — two mounting points, no tools beyond a screwdriver. If you're commissioning a new security head-end, AV rack, or network cabinet and need to close open rack units cleanly, the SB1-CP12 (often searched as SB1 CP12) is the workmanlike solution that gets the job done without overpaying for individual panels.

Blank panels are easy to overlook in a BOM, but skipping them creates real problems: open rack slots compromise airflow management, allow cable snag points, and expose internal components to dust accumulation. In a 24/7 surveillance or IT environment, those aren't cosmetic concerns — they're maintenance and liability issues. Buying in contractor-pack quantity keeps spares on the shelf for future expansions without re-ordering for every two-unit gap.

Key Features

• 1U Flanged Steel Construction: Each panel measures 1.75 in (4.4 cm) tall and 19 in (48.3 cm) wide — the EIA-standard 1U size that fits every conforming 19-inch rack on the market. The flanged style provides positive engagement against the rack rail face, eliminating the flex and rattle you get from unflanged snap-in alternatives. Steel material means these won't bow under adjacent equipment pressure over time.
• Textured Black Powder Coat Finish: The matte textured surface blends with Middle Atlantic enclosures and generic black rack frames without the visual mismatch of shiny or painted panels. In client-facing equipment rooms, uniform finish matters — powder coat also resists scratching during installation better than anodized or painted surfaces.
• Minimal Depth — 0.52 in (1.3 cm): At just over half an inch deep, these panels don't consume any meaningful front-clearance depth. That's relevant in shallow-depth wall-mount enclosures or any rack where front-door clearance is tight. No need to measure or reconfigure cable management before installing.
• Two Mounting Points: Standard two-point rack mounting means these seat flush and stay put. Two-point is appropriate for a dead-weight 1U panel — no structural reason to use four-point hardware here, which keeps the install fast.
• 12-Piece Contractor Pack: The SB1-CP12 ships 12 panels per pack in plain poly bags — no retail blister packaging to strip, no individually boxed units to unpack. For integrators stocking a service vehicle or job-site kit, bulk poly-bag format is the right call. A single pack covers a fully-populated 12U of gap-fill, or spreads across multiple smaller installs.
• Shipping Weight 10.84 lbs (4.9 kg) for 12 Panels: That per-panel weight of roughly 0.9 lbs is consistent with steel construction — light enough to handle in quantity but substantial enough to confirm these aren't thin-gauge sheet metal. Relevant when calculating rack weight budgets for floor-standing frames with manufacturer load ratings.

Integration & Compatibility

The SB1-CP12 is sized to the EIA-310-D standard for 19-inch rack equipment. It installs in any conforming 19-inch rack regardless of manufacturer — Middle Atlantic, Chatsworth, Rittal, Legrand, Panduit, or generic open-frame racks used in network switch and NVR deployments. The flanged style requires standard square-hole or threaded rack rails; confirm your rail type before ordering if you're running an older round-hole legacy frame. These panels do not require cage nuts in square-hole rails — standard M6 or 10-32 rack screws apply depending on your rail spec.

For system integrators building out IP camera head-end racks or PoE switch enclosures, maintaining a blanking-panel inventory is basic rack hygiene. Middle Atlantic's panel line integrates cleanly with their broader Middle Atlantic rack and enclosure catalog, and the SB1-CP12 finish matches across the product family.

Frequently Asked Questions

Q: What rack standard does the SB1-CP12 fit?

A: The SB1-CP12 panels are 19 inches wide and 1.75 inches tall (1U), conforming to EIA-310-D standard 19-inch rack sizing. They fit any conforming 19-inch rack regardless of manufacturer.

Q: Are these panels compatible with square-hole and threaded rack rails?

A: The flanged style works with standard rack mounting hardware. Square-hole rails use standard M6 or 10-32 rack screws; threaded rails use the appropriate machine screws for your rail spec. Confirm your rail type before ordering if you have a legacy round-hole frame.

Q: How many panels come in the SB1-CP12 pack?

A: The SB1-CP12 is a 12-piece contractor pack. Each pack contains 12 individual 1U flanged blank panels shipped in plain poly bags.

Q: What is the panel depth, and will it work in shallow enclosures?

A: Each panel is 0.52 inches (1.3 cm) deep — shallow enough to install in virtually any rack enclosure without front-clearance issues, including wall-mount and compact shallow-depth frames.

Q: What finish do the SB1-CP12 panels use?

A: Textured black powder coat over steel. The matte textured finish matches Middle Atlantic rack enclosures and most standard black rack frames, and resists scratching better than painted or anodized finishes during installation.

Q: How many mounting points does each panel have?

A: Two mounting points — standard for a 1U blank panel. This provides flush, rattle-free seating without requiring four-point hardware.

I spec the SB1-CP12 into almost every head-end rack BOM I put together — not because blank panels are exciting, but because leaving 0.52-inch-deep steel gap-fillers off the parts list is the kind of oversight that creates a service call six months later when a technician's cable snags on an open slot edge or the ops team complains about rack temps in a sealed cabinet. Twelve panels per contractor pack is the right quantity for a typical 4–6 rack deployment where you'll close 2–3 gaps per frame.

Technical Highlights:

• 19-inch × 1U Flanged Form Factor: The flanged edge locks flush against the rail face — no flex, no rattle under vibration. That matters in mobile deployments or anywhere HVAC creates airflow turbulence against rack doors.
• 0.52 in Depth: The sub-inch depth means you're not sacrificing front-door clearance in a shallow wall-mount enclosure. Most shallow frames run 12–18 inches of usable depth; at 0.52 inches, these panels are functionally invisible in the depth budget.
• Steel + Textured Powder Coat: Steel panels don't deform when adjacent 2U or heavier gear shifts during transport or installation. Textured powder coat holds up to the repeated surface contact that bare-rack installs accumulate over years.

Deployment Considerations:

• The SB1-CP12 ships in plain poly bags — no retail packaging. On a job site, keep the bags together until installation to avoid losing panels in a kit box. Twelve is the pack count, so order in multiples of 12 when estimating BOM quantity.
• Two mounting points means standard rack screws only — do not attempt to use cage nuts in a square-hole rail with this panel; it's not designed for that hardware stack and will seat unevenly.

For integrators commissioning NVR or network switch racks in a surveillance head-end, the SB1-CP12 is the straightforward answer to gap-fill: correct material, correct finish, correct quantity for a multi-rack job without over-ordering singles.
