Interchangeable inserts are disclosed for use in enclosures, such as underground enclosures. The interchangeable inserts include insert bodies that are configured to house stand-alone nuts and nuts contained within removable trays.

Interchangeable insert

Enclosures are disclosed for use in underground applications. The enclosures include walls with end portions that are angled outward with respect to a middle of the wall such that the enclosures can be stacked on top of one another despite a draft angle of the walls. The bottom corners of the enclosures are aligned with a top surface of the enclosure to allow stacking. The enclosures include an opening in the bottom such that when multiple enclosures are stacked on top of one another, the enclosures for a single larger enclosure that can be used in underground applications.

An end cap for a drainage system comprises a wall element having substantially the same profile as the cross-section of the end of the trench drain channel section. The wall element is adapted to be coupled to the trench drain channel section to form a terminal end of the channel section. At least one transverse groove is provided in the channel section so that, when the end cap is separated at the groove, the height of the end cap corresponds to the depth of the channel section. Typically, a plurality of transverse grooves are provided at spaced intervals along the vertical height of the wall element which correspond to different possible depths of the channel section. Thus, the end cap may be adapted to fit any one of a number of channel sections, regardless of depth. The end cap may further comprise a pipe coupler integrally molded with the wall element such that the wall element and coupler are substantially continuous. The pipe coupler extends outwardly from the wall element and defines an aperture having a predetermined shape and size for receiving a pipe, such that the pipe and at least a portion of the coupler are in fluid communication.
