Middle Atlantic DWR-18-26 18U Pivoting Wall Rack
The Middle Atlantic DWR-18-26 is an 18-space (18U) sectional wall rack built from steel with a black wrinkle powder coat finish, designed for installations where floor space is constrained and equipment still needs to be permanently housed and accessible. At 26 inches overall depth with 24 inches of usable depth, this rack accommodates full-depth network switches, NVRs, UPS units, and other enterprise-grade hardware without the compromise of a shallow-depth enclosure. If you're outfitting a wiring closet, security head-end, or network room where a full floor-standing cabinet isn't practical, the DWR-18-26 is the unit to specify.
Key Features
- 18U / 31.5 in. usable height: Provides 18 rack spaces in a wall-mounted footprint — enough to house an NVR, managed PoE switch, patch panel, and UPS together without stacking separate enclosures or losing floor real estate.
- 24 in. usable depth: Full-depth equipment fits without modification. Most enterprise switches and 1U/2U NVRs run 16–20 inches deep; the 24-inch usable interior handles them cleanly, leaving room for cable management at the rear.
- UL-rated 250 lb load capacity: UL-listed at 250 lbs (113.4 kg), which means you can populate all 18U with real gear — drives, switching hardware, power distribution — without exceeding the structural rating. That's not a nominal figure; it carries UL listing behind it.
- Seismic rated: The DWR-18-26 carries seismic certification (patent number 7278183 covers the seismic load design), making it a specifiable option for California and other jurisdictions with seismic requirements — relevant for school, government, and healthcare deployments where AHJ sign-off matters.
- TAA compliant, USA manufactured: Federal country of origin is USA and the unit is TAA compliant, so it can be purchased on GSA schedules and specified for federal, state, and local government projects without a waiver process.
- Forward rackrail configuration: The forward rackrail design mounts equipment at the front of the enclosure. This is the standard approach for wall racks — it keeps cable runs short and makes front-panel access straightforward without pulling the unit away from the wall.
- Forward compatible (DWR series sectional system): Marked forward compatible within the Middle Atlantic DWR series, meaning you can section additional rack modules onto this unit as your equipment density grows rather than replacing the entire enclosure.
- Black wrinkle powder coat steel construction: The steel chassis with wrinkle powder coat finish holds up in utility spaces — server closets, mechanical rooms, back-of-house wiring rooms — where painted surfaces take incidental contact regularly. More durable than flat powder coat in high-traffic installations.
- No front door (open frame): Ships without a front door, which reduces cost and improves airflow in open-air wiring closets. If physical security of the front panel is required, a compatible door accessory can be added separately.
- 83.99 lb product weight, 120.49 lb shipping weight: Plan for two-person installation. At roughly 84 lbs unloaded, this is not a solo-mount job, particularly when working at height. The 37-lb delta between product and shipping weight accounts for the packaging and hardware.
Integration & Compatibility
The DWR-18-26 accepts standard 19-inch rack-mount equipment across all 18U. It is part of the Middle Atlantic DWR pivoting wall rack family, and its forward-compatible design allows sectional expansion within that series. The 24-inch usable depth handles the majority of 1U and 2U network video recorders, managed PoE switches, and UPS hardware commonly deployed in security and AV head-end installations. For structured cabling planning, the 23.4-inch external width aligns with standard wall-mount bay sizing. Review your wall rack selection guide to confirm enclosure depth and load requirements before specifying — the 250 lb UL rating is generous for most 18U builds, but dense NVR-plus-UPS configurations should be totaled against that figure before ordering.
The DWR-18-26 (often searched as DWR 18 26) ships from the manufacturer in the USA and is available internationally per Legrand AV product data.
Frequently Asked Questions
Q: What is the usable rack depth of the DWR-18-26?
A: The usable depth is 24 inches (61 cm). The overall unit depth is 26 inches (66 cm), with the 2-inch difference accounted for by the enclosure walls and rackrail positioning. Most enterprise 1U/2U equipment fits without issue.
Q: Is the DWR-18-26 TAA compliant for government purchasing?
A: Yes. The DWR-18-26 is TAA compliant and manufactured in the USA (federal country of origin: USA), making it eligible for GSA schedule purchases and government project specifications.
Q: What is the UL-rated load capacity of the DWR-18-26?
A: The UL-listed load capacity is 250 lbs (113.4 kg). This is a verified UL rating, not a nominal manufacturer claim — relevant when specifying for projects that require UL-listed enclosures.
Q: Is the DWR-18-26 seismic rated?
A: Yes. The DWR-18-26 carries seismic certification under patent number 7278183, covering its seismic load design. This makes it specifiable in jurisdictions with seismic requirements such as California.
Q: Does the DWR-18-26 come with a front door?
A: No. The DWR-18-26 ships without a front door (open frame). If front-panel physical security is needed, a compatible door accessory from the Middle Atlantic DWR series can be added separately.
Q: Can I expand the DWR-18-26 with additional rack sections later?
A: Yes. The DWR-18-26 is marked forward compatible within the Middle Atlantic DWR sectional wall rack series, meaning additional rack sections can be joined to the existing unit as equipment density increases.
The DWR-18-26 is one of the few wall racks I'll spec without hesitation on security head-end builds — specifically because the UL-listed 250 lb load capacity is real load-rated steel, not a marketing number. At 18U and 24 inches of usable depth, you can fit a full security stack (NVR, managed switch, patch panel, UPS) in a wiring closet footprint and still have the seismic rating to satisfy a California inspector.
Technical Highlights:
- 24 in. usable depth vs. 26 in. overall: That 2-inch delta matters when you're measuring a tight wiring closet — plan to the 26-inch overall depth for wall clearance, not the usable figure.
- UL 250 lb load rating: On a fully populated 18U build with a 2U NVR (20–30 lbs), 24-port PoE switch (10–15 lbs), 1U PDU, and a mid-size UPS (40–60 lbs), you're well under the 250 lb ceiling — but spec it in writing for any government or institutional project where the AHJ will ask.
- Seismic certification (patent 7278183): Directly relevant in California, Oregon, Washington, and Nevada jurisdictions — this is what gets the wall rack approved on permit drawings without a special engineering waiver.
Deployment Considerations:
- At 83.99 lbs unloaded, this is a two-person lift for wall mounting. Factor that into your labor estimate — don't send a one-man crew to hang it at 7 feet.
- No front door ships standard. If the closet is accessible to non-technical staff or the client requires a lockable enclosure, price a compatible door accessory into the quote upfront rather than treating it as a change order.
Best fit for a school, municipal, or healthcare security head-end where you need TAA compliance, a UL-listed load rating, and seismic certification in a single wall-mount enclosure — and where floor-standing cabinets simply aren't an option.
