Middle Atlantic 500SP-7/8 500-Series Rack Face Plate with 7/8" Opening

Overview

The Middle Atlantic 500SP-7/8 is a single-opening face plate designed for the Middle Atlantic 500-series rack panel system. It provides a clean, finished 7/8" (22.2mm) diameter pass-through for cables, connectors, or small-diameter ports on a rack-mounted panel — eliminating blank holes and keeping your cable management tidy without forcing a full panel swap. If you're building out a structured rack enclosure and need a precisely sized opening for a specific connector type, the 500SP-7/8 (often searched as 500SP 7/8) is the component that gets you there without improvised cutouts or mismatched hardware.

Manufactured in the United States and weighing just 0.076 lbs, this face plate fits where a lightweight, purpose-made solution beats field fabrication every time. It's a small part, but in a structured cabling or AV/security rack build, using the correct panel component means a professional finish and long-term serviceability.

Key Features

• 7/8" (22.2mm) Opening Diameter: The precision-sized opening accepts a range of standard connector formats that fall within that diameter — RCA, small BNC, SMA, and similar. Using a panel with the correct hole diameter means your connector sits flush and secure, not rattling in an oversized cutout or forced into an undersized one.
• 500-Series Panel Compatibility: Designed specifically for Middle Atlantic 500-series rack accessories, this face plate installs without modification. Mixing components from the same series keeps your panel face consistent — uniform depth, aligned finishes, and no adapter hardware in between.
• Made in USA: Domestically manufactured, which matters for projects with TAA compliance requirements or procurement policies that specify US-origin hardware. For government, education, and enterprise deployments with supply-chain documentation requirements, the country of origin is a spec — not a footnote.
• 0.076 lbs Lightweight Construction: At under a tenth of a pound, the 500SP-7/8 adds effectively no load to your panel assembly. In a fully populated rack, every ounce matters — this component won't be the one pushing you over a weight threshold.
• Rack Accessory Category — Modular Build Approach: Rather than purchasing a pre-punched panel that may not match your connector mix, the 500-series modular approach lets you configure each opening individually. The 500SP-7/8 is one size option in that system, giving integrators the flexibility to build panels that match actual field requirements.
• Clean Cable Management Integration: A finished face plate opening is the difference between a rack that looks engineered and one that looks improvised. For structured rack enclosure builds in control rooms, security head-end closets, or AV equipment rooms, the panel finish is visible to end clients — it reflects build quality.

Integration & Compatibility

The 500SP-7/8 is part of Middle Atlantic's 500-series panel ecosystem. It installs into compatible 500-series blank panels or panel frames designed to accept modular inserts. Before ordering, confirm your existing panel or frame accepts 500-series inserts — the series designation is the key compatibility variable. This face plate does not include a panel frame; if you are building a new panel assembly, pair it with the appropriate 500-series base panel.

The 7/8" opening accommodates connectors and cable types that fall within 22.2mm outer diameter. If your connector requires a different opening size, Middle Atlantic offers additional 500-series face plate variants sized for other standard connector formats. Match the opening to your specific connector spec before ordering — the face plate opening is fixed and not field-adjustable. For integrators building out structured cable management systems, having the correct size on hand avoids return shipping delays on a component this small.

Frequently Asked Questions

Q: What is the opening diameter of the 500SP-7/8?

A: The 500SP-7/8 has a 7/8" (22.2mm) diameter opening. This is a fixed dimension — the face plate is not field-adjustable.

Q: Is the 500SP-7/8 made in the USA?

A: Yes. The 500SP-7/8 is manufactured in the United States, which supports TAA compliance and domestic procurement requirements.

Q: What panel series does the 500SP-7/8 fit?

A: The 500SP-7/8 is designed for Middle Atlantic's 500-series rack panel system. Confirm your base panel or frame accepts 500-series modular inserts before ordering — a panel frame is not included.

Q: What connectors fit through the 500SP-7/8 opening?

A: The 7/8" (22.2mm) opening accommodates connectors and cable jackets with an outer diameter at or below that dimension — common examples include RCA, small BNC, and SMA connectors. Measure your specific connector's outer diameter against 22.2mm to confirm fit.

Q: How much does the 500SP-7/8 weigh?

A: The 500SP-7/8 weighs 0.076 lbs, making it effectively negligible in rack weight calculations.

Q: Does the 500SP-7/8 include a panel frame?

A: No. The 500SP-7/8 is a face plate insert only. A compatible 500-series base panel or frame must be sourced separately if you are building a new panel assembly.

Jerry Tildsen

The Middle Atlantic 500SP-7/8 is the kind of component that separates a professionally finished rack build from a field-improvised one. The 7/8" (22.2mm) fixed opening is a deliberate spec — not an arbitrary hole size — and when you're terminating a panel face in a security head-end or AV control room, that precision is what keeps connectors seated correctly and panels looking intentional rather than patched together.

Technical Highlights:

• 7/8" (22.2mm) Opening: A fixed, precision-dimensioned opening that matches standard small-connector ODs — measure your connector's outer diameter against 22.2mm before ordering; there's no field adjustment once the plate is installed.
• Made in USA / Domestic Origin: Directly supports TAA-compliant procurement and supply-chain documentation requirements on government, education, and enterprise projects where country-of-origin is a contractual spec.
• 0.076 lbs Weight: Negligible load contribution — in a fully populated rack assembly with weight-per-U constraints, this component adds nothing meaningful to the count.

Deployment Considerations:

• The 500SP-7/8 is an insert, not a standalone panel — you need a compatible Middle Atlantic 500-series base panel or frame already on hand before this component does anything. Don't order the insert without confirming the frame is in the build.
• The 7/8" opening is fixed. If your actual connector has an OD outside that range, you need a different 500-series face plate variant — there's no field modification that's clean or repeatable at rack scale.

For security integrators building structured head-end closets or control room rack assemblies where the panel face will be client-visible, the 500SP-7/8 is the correct way to handle a 7/8"-class connector pass-through in a 500-series panel — domestically made, precisely sized, and zero improvisation required.
