Mounting rails 20" 4U

Mounting rails 20" 4U are metal rails designed for installation in server racks or cabinets. The 20" measurement refers to the length of the rails, which is a standard size for mounting equipment in rack enclosures.

The 4U specification indicates the height of the space the rails occupy in the rack. One "U" (rack unit) equals 1.75 inches, so 4U corresponds to 7 inches of vertical rack space. This height is used to mount devices that require four rack units.
