Middle Atlantic 500SP-11/2 Blank Rack Face Plate — 1.5-Inch Opening, 500-Series

Overview

The Middle Atlantic 500SP-11/2 is a blank face plate designed to close unused 1.5-inch front-panel openings in Middle Atlantic 500-series rack enclosures. If you have leftover gaps in a populated rack — common after repositioning equipment or leaving expansion slots open — this panel gives you a clean, finished appearance and prevents unwanted airflow bypass that disrupts cooling. It is a purpose-built fit for the 500-series, not a universal filler that requires shimming or modification.

The 500SP-11/2 (often searched as 500SP 11/2) is the right choice when you need to cover a 1.5-inch rack opening specifically within the 500-series enclosure family. Mounts to the front panel of the rack using standard hardware — no additional tools or brackets required beyond what the enclosure already provides.

Key Features

• 1.5-Inch Opening Coverage: Sized exactly for 1.5-inch rack openings in 500-series enclosures — no cutting, trimming, or shimming. A precise fit means the panel sits flush and does not rattle under vibration from adjacent equipment.
• 500-Series Compatibility: Engineered for Middle Atlantic's 500-series enclosure line, so hardware alignment, finish, and depth all match the enclosure's factory spec. Using a non-series-matched filler risks panel protrusion or recessing that looks unprofessional and may interfere with adjacent rack ears.
• Front-Panel Mounting: Installs at the front panel position, which is where airflow management matters most. Covering open slots here prevents hot exhaust air from recirculating into equipment intakes — a real factor in densely loaded rack accessory deployments.
• Blank Finish: No cutouts, no pre-drilled holes. Use it as-is for a completely sealed opening, or as a starting point if you need to field-punch for a connector or cable pass-through later.

Integration and Compatibility

The 500SP-11/2 is intended for Middle Atlantic 500-series enclosures only. Before ordering, confirm your enclosure is from this specific series — Middle Atlantic produces multiple enclosure families, and face plate sizing and mounting geometry differ across series. This panel will not adapt to non-500-series racks without modification. For racks used in network rack enclosure builds — security head-end rooms, AV control racks, or IT closets — maintaining proper blanking panel coverage is a baseline requirement for thermal management and a clean installation. See also the broader rack management category for cable organizers, vented panels, and patch accessories that complement this panel in a complete rack build.

Frequently Asked Questions

Q: What rack series is the 500SP-11/2 compatible with?

A: The 500SP-11/2 is designed specifically for Middle Atlantic 500-series enclosures. It covers a 1.5-inch front-panel opening in that series. It is not a universal blank and may not fit other Middle Atlantic series without modification.

Q: Does the 500SP-11/2 come with mounting hardware?

A: No package contents data is available in the product evidence. Contact your supplier to confirm what hardware is included, or verify against the Middle Atlantic 500-series installation guide.

Q: Can the 500SP-11/2 be used as a cable pass-through panel?

A: The panel ships blank with no cutouts. If you need a pass-through, you would need to field-modify it. For dedicated cable management, Middle Atlantic offers purpose-built pass-through and cable management accessories in the 500-series line.

Q: What is the opening size covered by the 500SP-11/2?

A: The 500SP-11/2 covers a 1.5-inch rack opening, as specified for the 500-series enclosure front panel.

Karl Wilson

The 500SP-11/2 is a purpose-built 1.5-inch blank face plate for Middle Atlantic 500-series enclosures — straightforward hardware, but the series-specific fit is what matters here. Using a non-matched filler in a 500-series rack often results in a panel that sits proud or recessed by a millimeter or two, which looks sloppy in a customer-facing head-end room and can create a pressure gap that throws off rack airflow.

Technical Highlights:

• 1.5-Inch Opening Size: Exact match to the 500-series front-panel slot spec — no shimming, no modification required for a flush, rattle-free fit.
• Front-Panel Mounting Position: Blanking panels at the front face are the primary lever for rack thermal management; an uncovered slot here allows warm exhaust to recirculate into intake zones on adjacent active equipment.
• 500-Series Series Match: Finish, depth, and hardware alignment are factory-matched to the 500-series enclosure line, which matters when the rack is visible to an end customer or subject to an installation audit.

Deployment Considerations:

• Confirm your enclosure is specifically a 500-series unit before ordering — Middle Atlantic's other enclosure families (BGR, WM, PD, etc.) use different face plate part numbers and opening geometries.
• If you anticipate adding equipment to this slot later, document the opening size now; a 1.5-inch slot limits what can be panel-mounted there without a different adapter or spacer.

Best fit for security integrators finishing a 500-series head-end rack in a commercial installation where a clean front-panel presentation and proper airflow management are both required — not a universal filler for mixed-brand racks.
