A system for a modular door for a building structure includes a door skeleton, an electrical interface, and a communication interface. The door skeleton includes one or more removable modular structures. At least one of the modular structures includes one or more electronic components and at least one of the electronic components is configured to receive and transmit electrical signals and data via the electrical interface and the communication interface, respectively.

Systems and devices for providing extension panels for doors. The extension panels may be physically coupled to the door using, for example, a bracket that may be coupled along a vertical edge and/or top edge or bottom edge of the door. In some instances, the bracket may include a channel that may be sized and shaped to receive and securely engage an elongated pin that may be physically attached to the extension panel. In some implementations, the bracket may include an H-shaped bracket that forms two cavities. One of the cavities may engage a portion of the extension panel and the other cavity may engage a portion of the door to physically couple the extension panel and the cavity.

An access door may include a core, first and second stiles defined along opposites sides of the core such that the core between the first and second stiles defines a recessed pocket with each of the first and second stiles defining a channel therein extending longitudinally along an inwardly-facing edge thereof, bottom and top elongated panels each defining tongue members at opposite sides thereof and configured to be received transversely in the recessed pocket with the tongue members received within the channels defined along the inwardly-facing edges of the first and second stiles, wherein, with the top and bottom elongated panels received in the recessed pocket, exterior faces of the first and second stiles, exterior faces of the top and bottom elongated panels, and an exposed surface of the recessed pocket between the top and bottom elongated panels define an exterior surface of one side of the door.

A plastic bottle storage apparatus for a garage door (PBSA) that is used in combination with an empty plastic bottle panel or strip which maintains empty plastic bottles prior to recycling. The PBSA has an upper section with an upper horizontal member, and a lower section with a lower horizontal member. An empty plastic bottle panel or strip with empty plastic bottles attached is secured to a hook clip or peg on the upper opening on the panel's or strip's upper end, and to a hook, clip or peg on an upper end of the opening on the panel's or strip's lower end. Once panels or strips with empty bottles are secured, the panels or strips with bottles can be maintained on the garage door indefinitely. The PBSA is able to compensates for the variations in length that occur as a sectional garage door opens and closes.

A barn door kit includes a plurality of pieces disassembled that are packaged in a much smaller footprint than an assembled barn door. The pieces that make up the door include a plurality of frame pieces and a plurality of panels. The frame pieces are connected together to create a frame of the door having a channel along an interior perimeter. The panels are configured to be inserted within the frame with the channel providing support. The panels include tongues on one side and corresponding grooves on the other side for securing adjacent panels together. The frame pieces and the panels are made from polyvinyl chloride (PVC). The kit also includes a track, roller brackets, handle and hardware. The hardware includes brackets mounted to upper edges of a right side frame and a left side frame to enable the roller brackets to be secured thereto.

A door system includes a door having a pocket in a face thereof, a panel sized and configured to be positioned within the pocket, and one or more connection features configured to selectively hold the panel in the pocket and allow for ready removal of the panel from the pocket.
