Universal 1U Rack Rails

The StarTech UNIRAILS1U is a set of adjustable steel rails that mount 19-inch servers or networking hardware into any standard rack. They support equipment weighing up to 25 kg or 55 lbs and include M5 screws, cage nuts and a wrench for immediate installation. The rails suit new builds or replacements for missing original hardware.

Passive Steel Construction

The rails are made entirely of steel with no moving parts, fans or power connections, so they add no noise or heat to the rack. Their 2.6 kg weight and 60 mm height leave airflow paths unaffected while the black finish matches typical cabinet interiors. Thermal and acoustic performance depends solely on the mounted equipment.

Adjustable Depth Fitting

Depth adjusts from 420 mm to 1054 mm to match a wide range of cabinet sizes, while the 465 mm external width aligns with standard 19-inch uprights. A removable rear cable management panel keeps wiring tidy without blocking rear access. Multiple hole patterns accommodate varied equipment mounting points.

Questions about this item

How do I install the UNIRAILS1U rails in a standard 19-inch rack, and what is the common mistake?

Attach the inner rail sections to the equipment using the included M5 screws and cage nuts, then slide the outer rails into the rack posts and secure them; the step often missed is adjusting the depth between 420 mm and 1054 mm before final tightening.

What maintenance or replacement will the UNIRAILS1U rails need over time?

The steel rails and removable rear cable management panel require no scheduled maintenance; only the M5 mounting screws or cage nuts may need replacement if threads strip during repeated equipment changes.

What is the first limit reached when the UNIRAILS1U rails hold a heavy server under sustained use?

The 25 kg (55 lbs) weight capacity is the primary limit; exceeding it risks bending the 2.6 kg steel rails or pulling the M5 fasteners from the rack posts.
