Rack rail StarTech 1U fixed 19" adjustable depth, steel, 481×1100 mm, M5

StarTech 1U fixed 19" adjustable depth rack rails provide a universal mounting solution for 1U equipment in standard 19-inch server racks. Constructed from steel with a black finish, the rails support a 481 mm (19") mounting width and an adjustable depth up to 1100 mm. Designed to accept M5 mounting screws, this product is intended to secure servers, switches and network appliances in cabinets and data centers while preserving full 1U rack space.

Advantages

The rail set converts non-rackmount or legacy equipment into a 1U rack-mountable configuration without requiring a shelf, using an open-frame cradle with three crossbars for stable support. Cold-rolled steel construction offers enhanced durability and a rated load capacity of up to 25 kg (55 lb). The adjustable depth accommodates a wide range of rack depths and configurations, and a removable rear cable management panel allows for cleaner cable routing and additional customization. Compatibility with standard M5 mounting screws simplifies installation in environments that follow EIA-310 19" rack standards.

Suitable for

• Mounting 1U servers and network appliances in standard 19" racks
• Installing non-rackmount desktop servers or KVM switches into a rack
• Replacing damaged or missing OEM rack rails on legacy equipment

How to use

Install the rails by attaching the front and rear mounting brackets to the vertical posts of a compliant 19" rack at the desired U position, adjusting the depth to match the equipment chassis. Place the equipment on the rail undercarriage and secure it using M5 screws where mounting holes align, or rest it on the crossbars for devices without matching hole patterns. Reattach the removable rear cable management panel if required for routing and strain relief.

Usage recommendations

Ensure the rack is rated to support the combined weight of the rails and mounted equipment and distribute weight evenly across rack units. Use appropriate M5 screw length to avoid damaging device chassis, and verify that the adjustable depth is locked before moving the rack. For heavy or valuable equipment, consider additional front mounting screws or support brackets to minimize cantilever stress.
