Abstract: Interior and exterior glazing strips hold a window glass or panel in place in a structural frame that has an opening slightly larger than the glass or panel. The glazing strips have a resilient reinforcing member with an elastomeric material extruded over and covering the reinforcing member. Receivers for the glazing strips have channels shaped to interlock with and hold the glazing strips around the periphery of the frame, and the reinforcing member extends from the gripping portion of the strip into the base of the strip interlocked with the channel. The reinforcing member resiliently presses the retainer portion of the glazing strip against the window glass or panel with a force of approximately 4-6 pounds per linear inch around the periphery of the window glass or panel.
