In one embodiment, a plastic door rail wedge for clamping a door panel to a door rail includes an elongate monolithic body. An inward face of the elongate monolithic body defines a clamping surface that configured to directly engages a side surface of the door panel. An upward end face of the elongate monolithic body defines a supporting surface that is configured to directly engage an end surface of the door panel. An outward face of the elongate monolithic body defines a camming surface that is angled with respect to the clamping surface. The door rail includes a frame with an opening and a bracket disposed within the opening of the frame. The bracket is configured to cam the first and second monolithic plastic door rail wedges toward each other to cause the monolithic plastic door rail wedges to clamp directly against the door panel.

Embodiments described herein may be directed to the functional application and method of use of a jacking screw for adjusting a window frame. In accordance with the present disclosure, adjusting the jacking screw may cause a first portion of the window frame to be lifted or lowered with respect to a second portion of the window frame. In doing so, a desired alignment of a window installed in the window frame may be achieved. This process may eliminate the use of shimming the underlying surface, thereby making it easier to install the window frame on surfaces that are not perfectly level.

Examples of glass adjustment assemblies arc described. An example glass adjustment assembly includes a locking member and a clamp that includes a base member with side extensions on either side. The example glass adjustment assembly also includes a horizontal connection member. The side extensions of the clamp are to be slidably mounted to the horizontal connection member. The locking member is to be variably attached to the horizontal connection member. The variable attachment is to apply controlled pressure on the base member of the clamp which is transmitted to a glass panel through an adhesive tape. The pressure applied to the glass panel may generate tension in a frame structure, which reduces sag and allows for thin members of the frame structure. In some examples, external hardware can attach to the vertical and/or horizontal connection members.

A rail assembly may include a housing with a cavity and a channel in the cavity. A cam may be disposed in the channel. The cam may include an elongated portion. One or more locks may be disposed in the channel and contact an outer surface of the cam. When the cam is rotated from the open position, the position of the locks may be adjusted to retain a panel disposed in the rail assembly. When the cam is rotated from the closed position to the open position, the position of the locks may be returned to the initial position and the panel may be moved and/or removed.

An improved door rail system for holding a panel, such as a glass panel, is presented. The door rail system includes a core rail and clamping rails having a wedging geometry so that when the clamping rails are actuated with respect to the core rail, clamping force is applied to the glass panel to secure the panel within the core rail. The improved door rail system accommodates panels of varying thickness, features the use of modular side covers and incorporates a door to door jamb adjustment device allowing for angular adjustments.

The rail assembly may be utilized with one or more panels, such as doors (e.g., glass), railings, etc. In various implementations, a rail assembly may include a housing with a cavity and a channel in the cavity. A cam may be disposed in the channel. The cam may include an elongated portion. One or more locks may be disposed in the channel and contact an outer surface of the cam. When the cam is rotated from the open position, the position of the locks may be adjusted to retain a panel disposed in the rail assembly. When the cam is rotated from the closed position to the open position, the position of the locks may be returned to the initial position and the panel may be moved and/or removed. The use of the cam in the rail assembly may allow adjustments to the position of the panel from an end of the panel and rail assembly.
