Middle Atlantic Products VSA-2744 VSA Series Heavy-Duty Telescoping Ventilated 19-Inch Rack Shelf, Adjustable 27–44 Inch Depth, 1.5-Inch Height

Condition: New and unused in original Middle Atlantic Products packaging. The shelf remains wrapped in protective plastic and includes the instruction sheet and mounting hardware. The outer cardboard packaging shows noticeable storage and handling wear.

The Middle Atlantic Products VSA-2744 is a professional heavy-duty telescoping rack shelf from the VSA Series, designed to support non-rackmount equipment inside standard 19-inch four-post racks and cabinets. Its primary feature is an adjustable mounting depth of approximately 27 to 44 inches (686–1118 mm), allowing the shelf to span between front and rear rack rails in deep AV, server, broadcast, networking, and telecommunications enclosures. The perforated steel platform provides extensive ventilation underneath installed equipment while also offering numerous openings that can be used for cable ties and equipment restraint.

Features

• 27–44 inch telescoping adjustment accommodates a wide range of distances between front and rear rack rails.
• Four-point support transfers the load to both the front and rear sections of the rack.
• Heavy-duty construction is designed for equipment substantially heavier than what typical front-mounted cantilever shelves can support.
• Extensively ventilated platform helps maintain airflow around heat-generating electronics.
• Numerous elongated ventilation slots can also provide convenient attachment points for cable ties or equipment restraints.
• Large usable support area accommodates deep or unusually shaped electronic equipment.
• Designed for professional AV, IT, server, broadcast, security, and telecommunications environments.
• Black powder-coated finish matches common professional rack systems and provides durable surface protection.
• Suitable for equipment that does not have its own 19-inch rack ears or mounting brackets.
• The VSA-series design may permit alternate mounting orientation where additional usable shelf width is needed, depending on the rack configuration.
• Important: “Telescoping” refers to adjustment of the shelf’s installation depth between rack rails. The VSA-2744 is not a pull-out drawer or sliding service shelf.

Applications

The Middle Atlantic VSA-2744 is suitable for:

• Professional AV racks
• Server and networking cabinets
• Telecommunications racks
• Broadcast installations
• Recording studios
• Live sound and stage systems
• Video surveillance installations
• DVR and NVR recorders
• Network appliances
• Non-standard server hardware
• UPS and backup-power equipment within applicable load limits
• AV receivers
• Professional amplifiers
• DSP processors
• Video processors
• Matrix switchers
• Automation and control processors
• Laboratory instrumentation
• Industrial electronics
• Equipment without factory rackmount ears

Use as Part of a Larger Rack System

The VSA-2744 is intended primarily for four-post rack systems with both front and rear vertical mounting rails. Its telescoping construction allows it to bridge the space between those rails and provide a stable platform for heavy equipment.

A typical installation may include:

• A 19-inch four-post rack or enclosure
• Middle Atlantic VSA-2744 shelf
• AV, IT, network, or security equipment placed on the shelf
• Cable ties or equipment restraints
• Vertical or horizontal cable management
• Ventilation or fan panels
• Rack PDU
• UPS
• Patch panels
• Network switches

Because of the potentially high supported load, the installer must also verify the load capacity of the rack enclosure itself, the strength and positioning of the rear rails, the mounting hardware, and the overall weight distribution. A high shelf load rating does not automatically mean that every rack cabinet can safely support the same load.

Cross-Referenced Models

Related VSA-series models include:

• Middle Atlantic VSA-1626 — heavy-duty telescoping shelf with an approximate 16–26 in. adjustable mounting depth
• Middle Atlantic VSA-2744 — heavy-duty telescoping shelf with a 27–44 in. adjustable mounting depth

The VSA-1626 serves a similar purpose in shallower enclosures, while the VSA-2744 is intended for deeper four-post rack installations.

Comparable Products

Comparable product types include:

• Middle Atlantic VSA-1626 — similar adjustable heavy-duty shelf for shallower racks
• Heavy-duty 19-inch four-post adjustable rack shelves
• Fixed ventilated four-point server rack shelves
• Adjustable-depth shelves for networking and AV cabinets
• Sliding rack shelves, when equipment needs to pull forward for service access; these are a different product type from the VSA-2744

Installation Notes

Before installation, measure the distance between the front and rear rack mounting rails. For this model, that distance should fall within the approximately 27–44 inch adjustment range.

The mounting-depth specification should not be confused with the maximum physical depth of the equipment placed on the shelf. The installed device must fit on the usable shelf surface and inside the cabinet while leaving sufficient clearance for connectors, cable bend radius, airflow, and service access.
