Middle Atlantic VSA-2744 Telescoping Heavy-Duty 1RU Rack Shelf
Overview
The Middle Atlantic VSA-2744 is a 1RU telescoping rack shelf built for installations where equipment depth isn't fixed at purchase time. With a mounting depth range of 27 to 44 inches, it accommodates everything from compact security appliances to deep rack-mount UPS units and NVRs without requiring a shelf swap when gear changes. The 400 lb weight capacity makes it one of the more capable single-rack-unit shelves in the Middle Atlantic rack accessory line — not a spec to take lightly when you're mounting dense storage arrays or multi-drive recorders.
At 19 inches wide and 1.5 inches tall (1 RU), the VSA-2744 fits any standard EIA 19-inch rack. If you're speccing a new rack build or retrofitting an existing enclosure, this shelf integrates without carving out additional rack space beyond the single unit it occupies.
Key Features
- 27–44 in Telescoping Depth Range: The shelf slides between 27 and 44 inches of usable mounting depth (69.3 cm to 111.8 cm), so you can fit shallow appliances and deep servers in the same rack without stocking multiple shelf SKUs. This is the primary reason integrators reach for this model over fixed-depth alternatives when equipment specs are still in flux at rack build time.
- 400 lb Weight Capacity: Rated at 400 lbs (181.4 kg), the VSA-2744 handles dense rack-mount equipment — multi-drive NVR chassis, industrial switching gear, or battery backup units — without the shelf becoming the failure point. Most comparable 1RU shelves top out well below this rating, so the capacity headroom is real.
- 1 RU Form Factor (1.5 in tall): Occupies exactly one rack unit at 1.5 inches of panel height. In a fully-loaded rack enclosure, that single-unit footprint matters — you're not trading two or three units of usable space for a shelf.
- 19 in Standard Rack Width: Fits any EIA 310-compliant 19-inch rack without adapters or spacers. This covers the full range of Middle Atlantic, APC, Tripp Lite, and third-party open-frame and enclosed racks in a typical security or AV infrastructure deployment.
- 4 Mounting Points: Four-point rack attachment distributes the load across both rails, which matters at 400 lbs of capacity — two-point designs flex under heavy equipment and can pull the shelf out of true over time. This is worth confirming when reviewing competitive options in the rack shelf category.
- 27.3 in Fixed Outer Depth: The shelf body itself is 27.3 inches deep (69.3 cm), providing a stable platform regardless of telescoping position. The telescoping rails extend to 44 inches; the base platform always gives equipment a consistent resting surface.
- Commercial-Grade Construction: Rated for the load demands of AV, security, and IT rack environments. At a shipping weight of 20.7 lbs (9.4 kg), the steel gauge reflects the 400 lb capacity rating — this isn't a thin-gauge consumer shelf dressed up for rack deployment.
Integration & Compatibility
The VSA-2744 is compatible with standard EIA 19-inch rack rails and integrates directly into Middle Atlantic rack enclosures and open-frame racks. The 4-point mounting pattern aligns with square-hole and round-hole rack rails — confirm your specific rail type before ordering if your enclosure uses non-standard toolless rails, as cage nuts or integrated clip nuts may be required.
Depth adjustment between 27 and 44 inches makes this shelf a practical choice for housing security NVRs, rack-mount PoE switches, or auxiliary servers in a network infrastructure rack where equipment varies by project. It also works as a temporary staging shelf during rack integration and testing before permanent equipment installation.
TAA compliance is not claimed for the VSA-2744. Federal procurement requirements (TAA/BAA) should be confirmed against the specific procurement vehicle — this shelf does not carry a TAA designation per manufacturer documentation.
For rack accessories pairing, consider cable management panels, rack-mount power strips, or vertical cable managers to complete a structured rack build alongside this shelf.
Frequently Asked Questions
Q: What is the depth adjustment range of the VSA-2744?
A: The VSA-2744 telescopes between 27 inches (minimum) and 44 inches (maximum) of mounting depth, making it adaptable to equipment of varying chassis depths within a single rack unit.
Q: How much weight can the VSA-2744 support?
A: The VSA-2744 is rated for a 400 lb (181.4 kg) weight capacity — sufficient for dense rack-mount equipment including multi-drive NVR units, UPS systems, and heavy switching gear.
Q: How many rack units does the VSA-2744 occupy?
A: The VSA-2744 occupies 1 RU (1.5 inches in height), fitting any standard EIA 19-inch rack without consuming multiple rack units.
Q: Is the VSA-2744 TAA compliant?
A: No. Per manufacturer documentation, the VSA-2744 is not TAA compliant. Verify procurement requirements before specifying this shelf for federal or government contracts with TAA restrictions.
Q: What rack rail types are compatible with the VSA-2744?
A: The VSA-2744 uses a 4-point mounting configuration and fits standard EIA 19-inch rack rails. Compatibility with specific toolless or non-standard rail systems should be confirmed with the rack enclosure manufacturer prior to installation.
Q: What is the outer body depth of the VSA-2744 shelf?
A: The shelf body is 27.3 inches (69.3 cm) deep. The telescoping rails extend the effective mounting reach to a maximum of 44 inches (111.8 cm).
The VSA-2744 earns its place in a rack build specifically because of that 27–44 inch telescoping range — when you're integrating a mix of security NVRs, managed switches, and appliances from different vendors, fixed-depth shelves create procurement headaches that this shelf eliminates. I've specified it on builds where the equipment list was still changing at installation day, and the ability to dial in the depth rather than swap hardware is worth the extra cost over a fixed-depth alternative.
Technical Highlights:
- 400 lb Weight Capacity: At 181.4 kg rated capacity in a single RU, this shelf handles even the densest rack-mount storage and UPS hardware without structural compromise — most 1RU shelves cap at 100–150 lbs, so the VSA-2744's rating is a genuine differentiator for heavy loads.
- 27–44 in Telescoping Range: The 17-inch adjustment window (69.3 cm to 111.8 cm) covers virtually the full depth spectrum of standard rack enclosures, from shallow wall-mount cabinets to deep floor-standing racks. One SKU handles both.
- 4-Point Mounting: Four-point rail attachment distributes load evenly across both rack rails — critical at 400 lb capacity where two-point shelves would introduce lateral flex and potential rail damage over time.
Deployment Considerations:
- The shelf body is 27.3 inches deep regardless of telescoping position — confirm your rack enclosure's interior depth accommodates the base shelf before ordering. In shallow wall-mount enclosures under 24 inches interior depth, this shelf will not fit even at minimum extension.
- TAA compliance is not listed for the VSA-2744 — if the project falls under federal procurement or a GSA contract with TAA requirements, this shelf cannot be specified without a waiver or an alternate model.
The VSA-2744 (often searched as VSA 2744) is the right call for security integrators building mixed-equipment racks in enterprise lobbies, server rooms, or command centers where NVR chassis, PoE switch stacks, and auxiliary appliances land in the same enclosure and equipment specs are still in motion at build time.
