Description

FIELD This disclosure relates generally to a duct for routing wires. More particularly, this disclosure relates to a duct for routing wires in a control panel enclosure. BACKGROUND Wire ducts are often used to route wires in an enclosure such as a control panel. Typically, rectangular ducts are used to route wires inside the enclosure. Rectangular ducts are not easily stackable when being stored or in transport prior to being installed in an enclosure. SUMMARY In some embodiments, a duct for routing wires in an enclosure includes a first sidewall including a first end and a second end opposite the first end. In some embodiments, a second sidewall includes a third end and a fourth end opposite the third end. In some embodiments, the duct includes a back wall. In some embodiments, the back wall includes a plurality of segments joined together at one or more bend lines. In some embodiments, the first end extends from the back wall. In some embodiments, the third end extends from the back wall. In some embodiments, in an uninstalled configuration, a first length from the second end to the fourth end is greater than a second length from the first end to the third end. In some embodiments, the first sidewall, the second sidewall, and the back wall are formed of a single piece, unitary construction. In some embodiments, in the uninstalled configuration, the back wall is in a dome shape. In some embodiments, in the uninstalled configuration, the back wall is in an inverted V shape. In some embodiments, in an installed configuration, the first length and the second length are equal. In some embodiments, the back wall is flexible to transition from the uninstalled configuration to an installed configuration. In some embodiments, in the installed configuration, the first sidewall is perpendicular to the back wall and the second sidewall is perpendicular to the back wall. In some embodiments, in the installed configuration, the first sidewall is parallel to the second sidewall. In some embodiments, the duct is made of a thermoplastic. In some embodiments, the duct is made of a polyvinyl chloride (PVC), a halide free poly (p-phenylene oxide) (PPO), a halide free polyphenylene sulfide (PPS), or combination thereof. In some embodiments, the first sidewall includes a plurality of fingers. In some embodiments, the second sidewall includes a plurality of fingers. In some embodiments, a duct for routing wires in an enclosure includes a first sidewall including a first end and a second end opposite the first end; a second sidewall including a third end and a fourth end opposite the third end; and a back wall. In some embodiments, the back wall includes a plurality of apertures configured to receive a fastener during installation of the duct. In some embodiments, the back wall is configured to flex between an uninstalled configuration and an installed configuration. In some embodiments, the first end extends from the back wall. In some embodiments, the third end extends from the back wall. In some embodiments, the first sidewall, the second sidewall, and the back wall are formed of a single piece, unitary construction. In some embodiments, in an uninstalled configuration, a first length from the second end to the fourth end is greater than a second length from the first end to the third end. In some embodiments, in the uninstalled configuration, the back wall is in a dome shape. In some embodiments, in the uninstalled configuration, the back wall is in an inverted V shape. In some embodiments, in an installed configuration, the first length and the second length are equal. In some embodiments, the back wall is flexible to transition from the uninstalled configuration to an installed configuration. In some embodiments, the first sidewall is perpendicular to the back wall and the second sidewall is perpendicular to the back wall. In some embodiments, in the installed configuration, the first sidewall is parallel to the second sidewall. In some embodiments, the duct is made of a thermoplastic.
