Abstract
Abstract Window unit for an oven door in which a one-piece spacing and clamping member is disposed between a pair of glass panels to maintain the panels in sealed, spaced-apart relation, the spacing and clamping member having integral flanges extending across the peripheral edges of the panels with portions of the flanges crimped over the outer edges of the panels to clamp the latter to the spacer. Molding strips are clamped between the glass and the crimped portions of the flanges and are engaged by flanges on the oven door to locate the unit within the door opening.
