Abstract: A glazing pocket filler is disclosed for use with a frame member having a glazing pocket of predetermined width for receiving a lateral edge of an infill panel. The glazing pocket filler comprises a filler panel having a length substantially corresponding to the width of the glazing pocket. A spring leg extends inward and forward from the filler panel and has a bearing surface located at a forward end thereof. The spring leg is configured such that when the filler panel is positioned across the glazing pocket, the bearing surface of the spring leg engages an inwardly convex portion of the frame member's forward glazing pocket wall to bias the rearward edge of the filler panel into engagement with the interior glazing pocket edge formation. Simultaneously the spring leg biases the inward face of the filler panel snugly against the outer edges of the frame member's front and rear glazing pocket walls. In this manner the filler panel is maintained in close engagement with the frame member.
