Middle Atlantic 8SP(14)RACK 22DEEP Maple - MBRK8-22

Middle Atlantic MBRK8-22 8U Maple Laminate Knockdown Rack

Overview

The Middle Atlantic MBRK8-22 is an 8-rack-unit, 22-inch-deep knockdown wood rack finished in maple laminate — a practical fit for boardrooms, executive offices, classrooms, and AV equipment closets where exposed metal enclosures are unwelcome. At 200 lbs rated capacity across a compact 15.63-inch overall height, it handles a full complement of NVRs, managed network switches, and amplifiers without requiring a dedicated server room. If you're integrating Middle Atlantic rack systems into a finished-space deployment, the MBRK8-22 (often searched as MBRK8 22) is the model to evaluate first.

Key Features

• 8 Rack Units / 14 in Usable Height: The 14-inch usable height accommodates eight standard 1U devices or a mix of 1U, 2U, and 4U gear — enough for a small security head-end (NVR + PoE switch + UPS + patch panel) in a single furniture-grade enclosure. The 1.63-inch gap between usable and overall height accounts for the top and bottom panels, so plan your U count against the 14-inch interior, not the 15.63-inch exterior.
• 22 in Depth / 21.5 in Usable: The 21.5-inch usable depth clears most 1U rack-mount NVRs and managed switches, which commonly run 14–20 inches deep. Deeper edge-of-rack servers won't fit — this is purpose-built for AV and light security gear, not datacenter hardware.
• 200 lb Weight Capacity: Two hundred pounds of rated load across 8U means you're not forced to cherry-pick lightweight gear. A fully populated NVR, UPS, and switch stack typically lands well under 80 lbs — this rack won't be the constraint.
• Maple Laminate Finish: The maple wood finish integrates into furnished environments — conference rooms, reception areas, home offices — where a black steel rack would stand out. The laminate surface resists minor scuffs better than painted wood.
• Knockdown Construction: Ships flat and assembles on-site, which matters when you're working in a finished building where getting a pre-assembled rack through a doorway or up a stairwell is the harder problem. Knockdown also reduces freight damage risk on long hauls.
• 10-32 Rack Rail Threading: Standard 10-32 tapped rails are compatible with the overwhelming majority of commercial rack-mount hardware — no cage-nut strips needed, no adapters required. Confirm your specific gear uses 10-32 fasteners; M6 threading (common on datacenter gear) won't engage correctly.
• Wood / Non-Conductive Enclosure: Wood construction means no grounding plane, which is a non-issue for typical AV and security deployments but relevant if your installation requires bonded metallic enclosures for EMI shielding or electrical code compliance. Verify local requirements before spec'ing.

Integration & Compatibility

The MBRK8-22 accepts any 19-inch rack-mount device with standard EIA-310 mounting ears. The 10-32 tapped rails work directly with rack screws supplied with most commercial NVRs, patch panels, and rack-mount UPS units. Cable management accessories from Middle Atlantic's wood rack line integrate with this enclosure — side panels, doors, and brush strips are available separately to complete a finished installation. For installations pairing this rack with IP cameras and network video recorders, the 8U capacity is sized for a typical 8–16 channel head-end: 1U NVR, 1U PoE switch, 1U patch panel, and 1–2U for a compact UPS. Consult a rack accessories guide when planning cable routing through a wood enclosure, since ventilation and thermal management require deliberate accessory selection — wood panels don't dissipate heat the way perforated steel does.

Frequently Asked Questions

Q: What is the usable rack space inside the MBRK8-22?

A: The MBRK8-22 provides 8 rack units (14 inches) of usable height. The overall external height is 15.63 inches — the difference accounts for the top and bottom panels of the enclosure.

Q: How deep can rack-mount equipment be to fit in the MBRK8-22?

A: Usable depth is 21.5 inches (the overall rack depth is 22 inches). Most 1U rack-mount NVRs, switches, and AV receivers fit comfortably. Avoid equipment exceeding roughly 20 inches of chassis depth to allow for cable connections at the rear.

Q: What type of rack rail threading does the MBRK8-22 use?

A: The rails are tapped 10-32, which is the standard for commercial AV and security rack hardware. M6 threading used on some datacenter equipment is not compatible — verify your gear's mounting screw specification before ordering.

Q: Can the MBRK8-22 be assembled on-site?

A: Yes. The MBRK8-22 is a knockdown design — it ships flat-packed and assembles at the installation location. This is particularly useful in finished spaces where a pre-built rack cannot be maneuvered through standard doorways.

Q: What is the maximum load the MBRK8-22 can support?

A: The rated weight capacity is 200 lbs (90.7 kg) across all 8U. A typical small security head-end — NVR, PoE switch, UPS — will be well under that ceiling.

Q: Is the MBRK8-22 suitable for installations requiring EMI shielding or a bonded metallic enclosure?

A: No. The MBRK8-22 is constructed from wood with a maple laminate finish and provides no metallic grounding plane. If your installation requires EMI shielding or a bonded enclosure per electrical code, a steel rack is the correct choice.

James Everett

The MBRK8-22 earns its place in finished-space security deployments specifically because of its 200 lb capacity combined with the maple laminate finish — you're not compromising structural load rating to get furniture-grade aesthetics. I've specified this rack for small commercial head-ends where the client simply won't accept exposed metal, and the knockdown construction is genuinely useful when you're working on the fourth floor of an occupied building.

Technical Highlights:

• 21.5 in Usable Depth: Clears virtually every 1U rack-mount NVR on the market — most run 14–18 inches. You'll have 3–7 inches of clearance for rear cable management, which matters more than most integrators plan for at spec time.
• 10-32 Tapped Rails: Direct-thread compatibility with standard commercial security and AV hardware means no cage-nut strip required. Faster installs, no lost hardware, no adapter SKUs to track.
• Knockdown / Flat-Pack Shipping at 32 lbs: The 32 lb shipping weight and flat-pack format make single-person transport to upper floors practical. A pre-assembled 8U steel rack of comparable capacity typically ships at 45–60 lbs fully crated.

Deployment Considerations:

• Wood construction provides zero EMI shielding and no ground plane — verify with your AHJ if a bonded metallic enclosure is required by local electrical code before the MBRK8-22 goes on the BOM.
• Ventilation is passive and depends on accessory selection; wood panels retain heat more than perforated steel. If you're populating all 8U with active gear, plan for a fan panel or leave at least 1U of open space for airflow.

The MBRK8-22 is the right call for a small 8–16 channel security head-end in a corporate reception area, classroom AV closet, or executive suite — anywhere the rack is in a viewable space and a steel enclosure isn't an option.
