Universal 1U 4-Post Rail Kit

This 1U universal rackmount rail kit supports rack mounted equipment such as servers, switches and UPS systems. It serves as an alternative to mounting ears or OEM server rails and is compatible with all major rack servers including Dell PowerEdge, HPE, Lenovo, IBM and Supermicro. The kit fits standard 19-inch 4-Post racks and cabinets.

Zinc-Plated 18-Gauge Steel Construction

Constructed from durable zinc plated 18-Gauge cold-rolled steel, the rails support equipment weighing up to 45 lbs (20 kgs). Compatible mounting holes include 10-32, 12-24 and standard universal square holes. A cable management bar is included to help organise cabling within the rack.

Adjustable Depth From 10 to 31.75 Inches

The mounting depth adjusts between 10 and 31.75 inches (254 - 806 mm) to accommodate varying chassis lengths. This range allows the same kit to secure short switches and deeper servers in the same rack row. The steel construction maintains rigidity across the full extension without permanent deformation.

Questions about this item

How do I install the rail kit in a 19-inch 4-post rack with square holes?

Slide the inner rails onto the equipment sides, then bolt the outer rails to the front and rear square holes using the included cage nuts and screws, adjusting the depth between 254 and 806 mm before tightening all fasteners.

Will the zinc-plated 18-gauge cold-rolled steel rails or the cable management bar need periodic replacement?

The rails and bar are built from zinc-plated 18-gauge cold-rolled steel for corrosion resistance and do not have a scheduled replacement interval; inspect mounting screws annually and retighten if vibration has loosened them.

At what load does the 45 lb (20 kg) weight limit become the limiting factor during continuous operation?

The 45 lb (20 kg) rated capacity is the structural limit; exceeding it risks rail deflection or mounting-hole damage, so keep the installed equipment at or below that weight for sustained use.
