StarTech CABSHELF116V2PK 1U Vented Universal Rack Mount Cantilever Shelf – 2-Pack

Overview

The StarTech CABSHELF116V2PK delivers two 1U vented cantilever shelves in a single purchase — a practical solution when you need to stage multiple pieces of passive equipment inside a standard EIA/ECA-310-E compliant rack without occupying drawer or chassis slots. At 15.7 inches of usable depth and a 44.1 lb per-shelf weight capacity, each shelf handles everything from patch panel overflow to keyboard trays, small UPS units, or NVR appliances that lack dedicated rack ears. The steel construction keeps the profile rigid without flex under sustained load, and the vented surface promotes airflow across whatever gear sits on top — a meaningful detail in dense rack builds where thermal management is already tight. Pair these with your network video recorders or other rack-mounted security appliances that need a stable platform without custom bracketing.

Key Features

• 44.1 lb (20 kg) weight capacity per shelf: Enough to support most 1U NVR appliances, KVM units, or small UPS devices without reinforcement. If your device tips the scale above 44 lb, step up to a heavy-duty shelf — this one is correctly sized for mid-weight gear.
• 15.7-inch (40 cm) mounting depth: Fits shallow to mid-depth racks. Standard 2-post and 4-post open-frame server rack cabinets work equally well. Measure your usable interior depth before ordering — deeper full-rack enclosures won't cause problems, but shallower 2-post telco frames might be a tight fit.
• 19.0-inch (48.3 cm) width — EIA/ECA-310-E compliant: Mounts directly to any standard 19-inch rack without adapter plates or custom hardware. Compliance with EIA/ECA-310-E means you're not gambling on fit in mixed-vendor environments.
• Vented steel deck: Passive airflow through the shelf surface reduces heat buildup on equipment sitting directly on the tray — worth having in populated racks where every degree matters.
• Steel frame construction: Resists racking and torque under asymmetric loads. Unlike plastic-composite shelves, the steel frame won't creep or deform over time in a always-on server room environment.
• 1U form factor (1.7 in / 4.3 cm height): Occupies a single rack unit, leaving adjacent slots available. Where rack space is measured in half-Us, a true 1U profile matters.
• 2-pack quantity: Two shelves per order — cost-effective for initial rack builds or when standardizing shelf positions across multiple cabinets in a single project.
• Black finish: Matches standard black rack enclosures for a clean, professional appearance in customer-facing or audited data closets.

Integration & Compatibility

The CABSHELF116V2PK installs into any 19-inch rack conforming to EIA/ECA-310-E — the same standard used by virtually every commercial rack manufacturer. This includes 2-post open-frame racks, 4-post open-frame racks, and enclosed rack cabinets. The cantilever design means no rear support post is required, making it viable in 2-post configurations where rear mounting points don't exist. Consult your rack accessories selection for complementary cable management, blanking panels, and PDU options that round out a complete rack build. This shelf works equally well in IT closets, security head-end rooms, and on-site NVR enclosures common in surveillance system deployments.

Frequently Asked Questions

Q: What is the maximum weight each shelf can support?

A: Each shelf in the CABSHELF116V2PK 2-pack supports up to 44.1 lb (20 kg). Do not exceed this load rating per individual shelf.

Q: Does the CABSHELF116V2PK require a rear mounting post?

A: No. These are cantilever shelves, which means they mount at the front rails only and do not require a rear support post. They are compatible with 2-post open-frame racks as well as 4-post and enclosed rack cabinets.

Q: What rack standard does the CABSHELF116V2PK conform to?

A: The shelves comply with EIA/ECA-310-E, the industry standard for 19-inch rack equipment. They will fit any rack built to this specification.

Q: How deep is each shelf, and will it fit in a shallow rack?

A: Each shelf provides 15.7 inches (40 cm) of usable depth. Verify that your rack's interior usable depth is at least 15.7 inches before installing. Very shallow 2-post telco frames under 16 inches of interior depth may not accommodate this shelf.

Q: Are both shelves identical, and how many rack units does each occupy?

A: Yes, both shelves in the pack are identical. Each occupies 1U (1.7 inches / 4.3 cm) of vertical rack space.

Q: What material are the shelves made from?

A: The shelves are constructed from steel with a black finish, providing a rigid, long-term-stable platform suitable for always-on equipment rooms.

Eden Phillips

The CABSHELF116V2PK is one of those items that solves a real rack-build problem without drama — two EIA/ECA-310-E compliant 1U cantilever shelves, each rated to 44.1 lb, shipping together. In a security head-end room where you're mixing NVR appliances, patch panels, and the odd keyboard tray, having a matched pair on hand from day one avoids the mid-project scramble for a second shelf.

Technical Highlights:

• 44.1 lb capacity per shelf: Comfortably handles most 1U NVR appliances and small UPS units. It won't work for a fully populated 2U server, but for the passive and light-active gear common in security closets, the load rating is appropriate.
• 15.7-inch depth on a cantilever mount: No rear post required. This matters most in 2-post open-frame racks where rear mounting hardware simply doesn't exist.
• Vented steel deck: The perforated surface isn't just aesthetics — it allows convection airflow under the device, which in a packed 1U environment can mean the difference between a device running at 45°C and 55°C over an 8-hour cycle.

Deployment Considerations:

• Confirm your rack's interior usable depth before ordering. The shelf is 15.7 inches deep — any rack enclosure with less than 16 inches of usable interior depth will create a fitment problem at the rear of the shelf.
• The 44.1 lb limit applies per shelf, not per pair. Do not stack heavy equipment across two adjacent shelves and assume the combined rating applies — each shelf is independently rated.

This pair is a natural fit for enterprise security head-end rooms and on-site NVR closets where a mix of rack-eared and non-rack-eared equipment needs a stable, organized home inside a standard 19-inch cabinet.
