19 Inch Rack Mount
19" Rack Mount
Because of 19 Inch Rack Mounts origin as mounting systems for railroad signaling relays, they are still sometimes called relay racks, but the 19 inch rack format has remained a constant while the technology that is mounted within it has changed to completely different fields. This standard rack mount arrangement is widely used throughout the telecommunication, computing, audio, entertainment and other industries, though the Western Electric 23-inch standard, with holes on 1-inch centers, prevails in telecommunications.
19 inch rack mounts are most often used to house professional audio and video equipment, including amplifiers, effects units, interfaces, headphone amplifiers, and even small scale audio mixers. They are also widely used for computer server equipment, allowing for dense hardware configurations without occupying excessive floor space or requiring shelving. A third common use for rack-mounted equipment is industrial power, control, and automation hardware, typically in 46U racks.

FasteningIn rack cases and rack servers the rack strip is tapped to receive threaded bolts. It is these bolts that hold equipment to the racks. Commonly cages nuts, bolts and washers are used to hold everything tightly in place such as the standard pack Pro Audio Stash stocks.
The types of screws used on a rack are dependant on the tapped hole. In the USA imperial rack rail is the common rack rail used for 19 inch racks. Imperial rack rail requires M5 screws and fasteners. In Europe the full hole rack rail is more common (see for more details). Rack rail in Europe is also referred to a rack strip and uses M6 screws.
| Front and Back mounting Rack EquipmentMost rack accessories such a rack panels and static rack panels only mount to the front rack rails of server or rack case. However, heavy equipment is often mounted in drawers or trays attached to both the front and back rails. These drawers and trays are on slides allowing equipment to be easily accessed.

Types of RackPro Audio Stash stock a range of 19" hardware and rack cases which are used in different circumstances. As explained above it is possible to build a 19" rack mount server using rack mount components.
It is also possible to buy pre built racks such as the common flat pack rack cases or the polyethylene cases used by the music industry to transport electronic equipment to gigs. A Gator Case is classic example of a polyethylene case pre built with rack rail, so it ready to use the moment you buy it.
| Rack UnitA rack unit is a measurement used to describe the height in a rack. One rack unit (know as 1U) is 1.75" (44.45mm) in height. These U's are referred to when choosing rack equipment, because devices, rack drawers and rack shelves will be a certain U in height e.g. 2U, 3U, 4U etc
