Abstract
Abstract A resilient glazing gasket for positioning and sealing window panes within a rigid channel frame. The gasket, in cross section, has an outer strip and a normally extending intermediate web to be positioned between the pane and one edge of channel leg. A deformable locking flange extending from the intermediate web is adapted to be slipped past the edge of the channel leg and then pushed into the channel by a wedge which is forced into locking position between one side of the glass pane and the other channel leg. The wedge and locking flange include complementarily shaped configurations which engage with each other to hold the wedge and locking flange in position within the channel.
