Middle Atlantic Wide Unit Shelf SYS 17.5D - WUSS17.5

Middle Atlantic WUSS17.5 Wide Unit Shelf System 17.5D

Overview

The Middle Atlantic WUSS17.5 is a rack-mount unit shelf designed for AV and security integrators who need a fixed platform for non-rack-mount gear inside a standard rack enclosure. At 17.5 inches deep and rated to hold 50 lbs, it gives you a solid surface for media converters, unmanaged switches, battery backups, or any component that doesn't come with its own rack ears. If you're building out a rack accessory stack and need a general-purpose shelf that won't flex under real load, the WUSS17.5 is a practical, no-surprise choice from the Middle Atlantic rack solutions line.

Key Features

• 17.5-Inch Depth: At 17.5 in (44.5 cm), this shelf accommodates most standard 1U and 2U components — deep enough to seat a full-size UPS or media chassis without overhang risk.
• 50 lb Weight Capacity: The 50 lb (22.7 kg) rated load means you can place real equipment here — a multi-port PoE injector, a battery block, a small NVR — without worrying about shelf deflection under sustained use. This isn't a light-duty catch-all.
• 17.56-Inch Width: Width of 17.56 in (44.6 cm) aligns to standard rack interior dimensions, keeping clearance predictable on both sides when fitted inside a rack enclosure.
• 5.19-Inch Profile Height: At 5.19 in (13.2 cm) tall, this shelf occupies roughly 3U of vertical rack space — plan your rack layout accordingly if you're integrating it alongside NVRs and network switches in a dense build.
• Rack Mount Installation: Mounts directly into standard rack rails — no shelf-specific hardware gymnastics. Integrators familiar with Middle Atlantic enclosures will have this seated in minutes.

Integration and Compatibility

The WUSS17.5 fits inside Middle Atlantic rack enclosures and is compatible with standard EIA 19-inch rack rail systems. It works as a static platform for non-rackable components in security head-end rooms, IT closets, and AV equipment bays. For shelf placement planning in mixed-component racks, pair this with a rack layout guide to allocate U space correctly before installing. Note: this is a passive shelf — no cable management, no ventilation features — so factor in airflow if the gear sitting on it generates meaningful heat.

The WUSS17.5 comes up regularly on mid-size security head-end builds where you have a rack full of IP cameras feeding an NVR, a managed switch, and inevitably a couple of components — a fiber media converter, a small UPS, an unmanaged injector — that don't have rack ears. The 50 lb capacity is the number that actually matters here: most shelves in this class are rated to 25–30 lbs, and integrators routinely underestimate how fast real gear adds up.

Technical Highlights:

• 50 lb Load Rating: Double what many competing shelves carry — you can seat a compact UPS or a multi-port PoE injector without being near the rated limit, which matters for long-term reliability.
• 17.5-Inch Depth: Matches the interior depth of most Middle Atlantic rack enclosures, so the shelf surface uses the full available footprint without dead space or overhang.
• 5.19-Inch Height: Plan for 3U consumed in your rack layout. On a 12U or 16U wall enclosure, that's a real slice — don't add this shelf as an afterthought in a near-full rack.

Deployment Considerations:

• This is a passive shelf — no integrated ventilation or cable management. If the component sitting on it runs warm (a compact UPS under load, for instance), verify you have rack-level airflow before committing the placement.
• At 5.19 inches tall, the WUSS17.5 takes up meaningful vertical space. In a dense head-end rack with an NVR, patch panel, and switch already installed, audit your available U count before ordering.

The WUSS17.5 is the right call for security head-end rooms and IT closets where you need a solid, rated platform for non-rackable gear and can't afford a shelf that flexes or fails under a 30+ lb battery backup. It's not for minimalist shallow-rack builds where every U and every inch of depth is already spoken for.
