4U 2Post Conversion Kit

The BFKK 4U 2Post Conversion Kit adapts a standard two-post relay rack so that four-post server and networking equipment can be mounted in 4U of vertical space. It is intended for installers who need to add rack-mount servers to an existing two-post frame without replacing the whole cabinet.

Easy installation with included hardware

All mounting hardware ships in the box and the brackets align with standard EIA 19 inch and 23 inch telecommunications racks as well as 3 inch uprights. The server chassis must not exceed 17.72 inches in depth when attached to its rail kit, otherwise the conversion brackets will not provide enough rear support.

Solid steel rated for 50 pounds

The solid steel construction supports up to 50 pounds (22 kilograms) per kit, allowing sustained loading of typical rack-mount servers and network appliances. Multiple kits can be coupled together with the supplied hardware when deeper or taller equipment configurations are required.

Questions about this item

How do I verify the conversion kit is securely holding my 4U server after installation?

Confirm the server chassis depth does not exceed 17.72 inches and that the total equipment weight stays within the 50 pound limit; the solid steel brackets should show no flex when fully tightened.

What hardware is included and what must I source separately for a 4U 2-post conversion?

The kit supplies all brackets and coupling hardware to join multiple conversion sizes; you must provide the 2-post relay rack with 3-inch uprights and the server rail kit that matches your equipment.

Which bracket height should I choose for a standard 4U server chassis?

Select the 4U size bracket to match the server height; 2U, 3U, 5U and 7U brackets are also available if you need to convert a different rack space.
