Trunk gland adapters and related trunk gland units and methods of connecting trunk cables to fiber optic enclosures
Trunk gland adapters include an adapter body having an internal bore that is sized to receive a trunk cable gland so that a front end of the trunk cable gland extends through a front opening of the internal bore and a plurality of attachment clips that are configured to releasably attach the adapter body to a mounting aperture in a wall of a fiber optic enclosure. Related trunk gland units and methods of routing a trunk cable into an enclosure are also disclosed.

an adapter body having an internal bore that has a front opening and a rear opening, the internal bore sized to receive a trunk cable gland so that a front end of the trunk cable gland extends through the front opening; and
a plurality of attachment clips that are configured to releasably attach the adapter body to a mounting aperture in a wall of a fiber optic enclosure,
wherein the front opening of the internal bore has a first diameter and the trunk cable gland includes a nut that is received on the front end of the trunk cable gland, the outer surface of the nut defining a second diameter that is larger than the first diameter.
2. The trunk gland adapter of claim 1 , wherein the internal bore extends in a longitudinal direction, and wherein the adapter body includes a longitudinal slot that extends from the front opening to the rear opening and that provides access to the internal bore.
3. The trunk gland adapter of claim 1 , wherein the attachment clips comprise snap clips that have release tabs that extend rearwardly beyond the rear opening of the adapter body.
4. The trunk gland adapter of claim 1 , wherein an inner surface of the adapter body includes a plurality of stops that are configured to prevent rotation of the trunk cable gland when the trunk cable gland is fully received within the adapter body.
5. The trunk gland adapter of claim 4 , wherein the plurality of stops comprise a plurality of ridges projecting inwardly from the inner surface of the adapter body into the internal bore that generally define a hexagon.
6. The trunk gland adapter of claim 4 , wherein the plurality of stops comprise a first plurality of ridges projecting inwardly from the inner surface of the adapter body into the internal bore that generally define a first hexagon and a second plurality of ridges projecting inwardly from the inner surface of the adapter body into the internal bore that generally define a second hexagon that is larger than the first hexagon.
7. The trunk gland adapter of claim 1 , wherein the adapter body is free to rotate within the mounting aperture when the adapter body is installed in the mounting aperture.
8. The trunk gland adapter of claim 1 , wherein the adapter body includes at least one radially outward projecting stop.
9. The trunk gland adapter of claim 1 , further comprising a detachable plug that substantially covers the front opening of the internal bore.
10. A trunk gland unit, comprising:
a trunk cable gland having a cable gland body that has a front end that includes external threads, a rear end opposite the front end, a cable passage extending longitudinally from the front end to the rear end, and a removable nut that is threaded onto the external threads on the front end of the cable gland body; and
a trunk gland adapter having an adapter body having a front wall that has a front opening, a rear wall that has a rear opening and an internal bore that extends from the front opening to the rear opening,
wherein the cable gland body is received within the internal bore so that the front end of the trunk cable gland extends through the front opening of the front wall,
wherein the trunk cable gland and the trunk gland adapter are configured to capture a wall of a fiber optic enclosure between the trunk gland adapter and the removable nut so that a portion of the adapter body extends through the wall of the fiber optic enclosure when the trunk gland unit is installed in an aperture in the wall of the fiber optic enclosure, and
wherein the front opening of the front wall has a first diameter and the removable nut has a second diameter that is larger than the first diameter.
11. The trunk gland unit of claim 10 , further comprising a plurality of attachment clips extending rearwardly from the adapter body that are configured to releasably attach the adapter body within the mounting aperture in the wall of the fiber optic enclosure.
12. The trunk gland unit of claim 11 , wherein the attachment clips comprise snap clips that have release tabs that extend rearwardly beyond the rear opening.
13. The trunk gland unit of claim 10 , wherein an inner surface of the adapter body includes a plurality of stops that are configured to prevent rotation of the trunk cable gland when the trunk cable gland is fully received within the trunk gland adapter.
14. The trunk gland unit of claim 13 , wherein the plurality of stops comprise a plurality of ridges projecting inwardly from the inner surface of the adapter body into the internal bore that generally define a hexagon.
15. The trunk gland unit of claim 14 , wherein the plurality of stops comprise a first plurality of ridges projecting inwardly from the inner surface of the adapter body into the internal bore that generally define a first hexagon and a second plurality of ridges projecting inwardly from the inner surface of the adapter body into the internal bore that generally define a second hexagon that is larger than the first hexagon.
16. The trunk gland unit of claim 10 , wherein a rear end of the adapter body includes at least one radially projecting stop that is sized to prevent the trunk gland adapter from passing completely through the aperture in the wall of the fiber optic enclosure.
17. The trunk gland unit of claim 10 , wherein the removable nut has an outer diameter that is smaller than a diameter of the aperture in the wall of the fiber optic enclosure.
18. A trunk gland unit, comprising:
a trunk cable gland having a cable gland body that has a front end that includes external threads, a rear end opposite the front end, a cable passage extending longitudinally from the front end to the rear end, and a removable nut that is threaded onto the external threads on the front end of the cable gland body; and
a trunk gland adapter having an adapter body having a front wall that has a front opening, a rear wall that has a rear opening and an internal bore that extends from the front opening to the rear opening,
wherein the cable gland body is received within the internal bore so that the front end of the trunk cable gland extends through the front opening of the front wall,
wherein the trunk cable gland and the trunk gland adapter are configured to capture a wall of a fiber optic enclosure between the trunk gland adapter and the removable nut so that a portion of the adapter body extends through the wall of the fiber optic enclosure when the trunk gland unit is installed in an aperture in the wall of the fiber optic enclosure, and
wherein the internal bore extends in a longitudinal direction, and wherein the adapter body includes a longitudinal slot that extends from the front opening to the rear opening and that provides access to the internal bore.
