Rackmount effects units are typically built in a thin metal chassis with ''rack ears'' designed to be screw-mounted into the rack rails of a [[19-inch rack]] that is standard to the [[music technology (electronic and digital)|music technology]] industry. Rackmount effects have a standardized 19-inch width, and height of 1 or more [[Rack unit|rack unit(s)]]. Devices that are less than 19 inches wide can sometimes be made rackmount-compatible via special rackmount adapters.<ref>{{Cite book|last=Ashton|first=Adrian|title=The Bass Handbook|publisher=Hal Leonard|year=2006|page=92

A rackmount effects unit may contain [[electronic circuit]]ry identical to a stompbox's, although its circuits are typically more complex. Unlike stompboxes, rackmounts usually have several different types of effects.<ref>{{Cite book|last=Ashton|first=Adrian|title=The Bass Handbook|publisher=Hal Leonard|year=2006|pages=91–92|isbn=9780879308728|url=https://books.google.com/books?id=I97xJYZC2lIC&pg=PA92}}</ref> Rackmount effects units are controlled by knobs, switches or buttons on their front panel, and often remote-controllable by a [[MIDI]] digital control interface or pedal-style ''foot controller''.<ref>{{Cite book|last=Levitin|first=Dan|title=From Demo Tape to Record Deal: Handy Guide|publisher=Alfred Music|year=1992|page=26|url=https://books.google.com/books?id=IxeGcwKrJUUC&pg=PA26|isbn=0-88284-494-6}}</ref>

Rackmount effects units are most commonly used in recording studios and [[front of house]] [[live sound mixing]] situations. Musicians may use them in place of stompboxes, as use of a rack can offer space for conveniently mounting additional rackmount equipment or accessories. Rackmounted effects units are typically mounted in a rack, which may be housed within a road case, a durable case with removable access panels that protect the equipment within during transportation. Because of this, rackmount effect units are not always designed with durable protective features such as corner protectors which are used on stompboxes and amps that are designed to be transported as standalone units.
