Rack shelf 19" 250 mm 1U by CATerpillar (TN-19-250-1U-GY)

CATerpillar 19" rack shelf TN-19-250-1U-GY is a compact 1U shelf with 250 mm depth designed for installation in standard 19-inch server and network racks. The shelf provides a stable, flat support surface for devices and accessories that do not require a dedicated rackmount chassis or active ventilation. Its slim 1U profile conserves rack space while offering quick placement for small equipment in server rooms, telecom cabinets and equipment closets.

Advantages

The shelf combines a minimal 1U height with a 250 mm depth to accommodate compact devices without occupying multiple rack units. Constructed for rack compatibility, it offers secure mounting and a uniform load-bearing surface that simplifies organization of non-rackmount items. Its neutral grey finish integrates with common rack interiors, enabling tidy cable routing and easy access to supported equipment.

Suitable for

• Mounting small switches, external hard drives, media players or single-board computers
• Holding power supplies, patch panels or cable management accessories
• Temporary placement of laptop or diagnostic tools inside a rack
• Use in server rooms, telecom cabinets, equipment closets and test benches

Key specifications

• Form factor: 1U rack shelf for 19-inch racks
• Depth: 250 mm
• Mounting: front and rear rack-mountable in standard 19" rails
• Surface: flat support surface for non-rackmount equipment

How to use

Install the shelf into the desired 1U position by aligning the mounting holes with the rack rails and securing it with appropriate rack screws or cage nuts. Place equipment centrally on the shelf to distribute weight evenly and avoid overhanging the front or rear edges. Ensure that the load does not exceed the rack shelf's rated capacity and that airflow around heat-generating devices is sufficient. For devices requiring cabling, route cords through existing cable management openings to maintain clearance and accessibility.

Usage recommendations

Use the shelf for compact or temporary equipment that does not need ventilated or fixed mounting. Verify weight capacity before loading heavy components and maintain proper cable organization to prevent strain on connectors and to preserve airflow within the rack.
