Glazing panel installation structure and method

摘要

An installation structure and method for installing and removing a sacrificial glazing panel in a frame having a perimeter channel in which a deeper channel section is formed in the frame receiving an edge of the glazing panel to allow forcible shifting of the glazing panel so that an opposite edge clears the lip of an opposite channel section during installation and removal. A positioner element such as bowed leaf spring may be installed to reposition the glazing panel after the glazing panel is released so that the opposite edge is located to be retained by the lip after release.
