ABSTRACT:
This peripheral member is for use in a frame holding one or more window panes and in a framework for attachment along the inside of a window opening in a building structure. It has a hollow rectangular main body and a narrower rectangular extension. The main body and the extension form a right-angled inside corner where their adjoining sides present intersecting longitudinal recesses. These sides of the main body and the extension have longitudinal grooves located away from the inside corner. The remaining faces of the main body and the extension are flat, including a face on the extension that is a co-planar continuation of a corresponding face on the main body.
