Middle Atlantic 2 Space (3 1/2IN. ) 1/8IN. Flat Aluminum Blank Panel Black Brushed - HBL2

Middle Atlantic HBL2 2U Flat Aluminum Blank Rack Panel

Overview

The Middle Atlantic HBL2 is a 2-rack-unit (3.5 in.) flat aluminum blank panel designed to fill open bay space in 19-inch equipment racks. At just 0.08 inches deep, the HBL2 sits flush with adjacent rack-mount gear, keeping airflow paths clean and rack aesthetics consistent in AV equipment rooms, security head-end enclosures, server closets, and communications infrastructure buildouts. If you have open rack real estate between devices and need a clean, permanent fill — not a temporary placeholder — this is the panel to reach for.

The brushed and anodized black aluminum finish is purpose-matched to the standard Middle Atlantic rack panel lineup, so it blends cleanly alongside mounted NVRs, patch panels, and power distribution units without the color drift you get from mixing finished and raw metals over time. Two mounting points anchor it to standard 19-inch rack rails.

Key Features

• 2U / 3.5-inch panel height: fills exactly two rack units of dead space — the most common gap size left after deploying 1U or 3U gear. No cutting, no shimming, no jury-rigging with cardboard or zip-tied cable managers.
• 19-inch standard width (48.3 cm): fits any EIA-310-compliant 19-inch rack — wall-mount enclosures, open-frame racks, server cabinets, and AV equipment rigs. No adapter brackets needed.
• 0.08-inch flat profile (0.2 cm depth): essentially flush-mount. The shallow depth means nothing protrudes into the interior rack column, leaving full cable management clearance behind the panel and unobstructed airflow through any adjacent ventilation.
• Aluminum construction: lighter than steel blanks and corrosion-resistant for the life of the installation. At 0.8 lbs shipping weight (0.4 kg), the HBL2 won't add meaningful load to wall-mount rack enclosures where total weight matters.
• Black brushed and anodized finish: anodizing is a hardened surface treatment, not paint — it won't chip, peel, or scratch off with repeated panel swaps during equipment changes. The brushed texture matches Middle Atlantic's standard rack family for a clean, uniform equipment room appearance.
• Two mounting points: secures to both rail columns for a stable, rattle-free fit. Single-point or clip-on blanks can vibrate loose in environments with fan vibration or mechanical equipment nearby; two-point fastening eliminates that.
• Ships as individual unit (package qty 1): order exactly the quantity you need per project rather than buying a pack with leftover panels sitting in a storage room for years.

Integration and Compatibility

The HBL2 is compatible with any standard rack-mount enclosure or open-frame rack using EIA-310-D 19-inch rail spacing. It pairs naturally alongside Middle Atlantic rack enclosures and accessories and drops into any third-party 19-inch rack without modification. For security system head-ends, use it to blank unused bays in racks housing network video recorders, PoE switches, and video management appliances — keeping dust out of the chassis and satisfying data center or IT room tidy-rack requirements. Also appropriate for rack power distribution buildouts where leaving open bays is a safety or cooling concern.

Frequently Asked Questions

Q: What rack unit size is the HBL2?

A: The HBL2 is a 2U panel, measuring 3.5 inches (8.9 cm) in height. It fills exactly two rack units of open bay space in a standard 19-inch rack.

Q: Will the HBL2 fit a standard 19-inch rack?

A: Yes. The HBL2 is 19 inches (48.3 cm) wide with two mounting points, compatible with any EIA-310-compliant 19-inch rack rail system — including open-frame racks, wall-mount enclosures, and enclosed server cabinets.

Q: How deep does the HBL2 extend into the rack interior?

A: The HBL2 has a depth of just 0.08 inches (0.2 cm) — it is essentially flush-mount and does not protrude into the rack interior, keeping cable management and airflow paths clear.

Q: What finish does the HBL2 have, and will it match other Middle Atlantic panels?

A: The HBL2 has a black brushed and anodized aluminum finish. Anodizing is a hardened surface treatment that resists chipping and peeling, and it is consistent with the standard Middle Atlantic rack panel family.

Q: Does the HBL2 come with mounting hardware?

A: The product ships as one panel unit. Mounting screws are standard rack fasteners (10-32 or M6 depending on your rail type) — use whatever hardware is standard for your rack installation.

Q: Can I order a single HBL2 or is it sold in multipacks?

A: The HBL2 is sold individually (package quantity 1), so you can order exactly the number of panels your project requires without purchasing a multipack.
