Abstract: A door system having a door shoe including a first shoe member and a second shoe member that provide a thermal break between the members, which reduces heat transfer between the members. One or more gaskets may be operatively coupled to the first shoe member or the second shoe member. The first shoe member and the second shoe member can be operatively coupled to the door to cover different sized gaps located between the bottom edge of the door and a floor. As such, the door shoe disclosed herein may be used to cover different size gaps, provide a thermal break between the members to aid in fire resistance, and be easily installed on doors without having to remove the door from the frame.

Abstract: A threshold system and threshold insert for transitions through doorways. An insert for a threshold saddle to be used with a door includes an elongated member for providing a seal along a bottom edge of the door and to be received in a seat in the saddle. The insert defines a door engagement surface adapted to extend across both the seat and the change in elevation to engage the door to provide the seal. When installed for use, the door engagement surface, the saddle adjacent to the sides of the seat, or both provide an overall slope of at least or approximately 2 units horizontal to 1 unit vertical. A threshold system includes a saddle and the insert. The door or an appurtenant door shoe may have an angled surface to interface with the door engagement surface of the insert.

Abstract: A kit for mounting a frame in a partitioning structure such as a door, and a door including a vision lite. The kit includes a male frame half, a female frame half, and threaded fasteners. The female frame half defines an elongated channel, where the channel includes a bottom with walls extending therefrom with a width adapted to receive a threaded fastener. The first frame piece and the second frame piece are configured to be mounted to each other when the threaded fasteners extend through the first frame piece and into the channel. An installation of such a kit in a door, with window glass, may provide a vision lite in the door. The channel may be configured such that the threaded fasteners penetrate the bottom of the channel when the first frame piece and the second frame piece are installed. The threaded fasteners may be self-tapping screws.
