Abstract
A corner member for locating at right angles spacer strips of a sealed window unit includes a pair of legs at right angles each for extending into an adjacent end of one of the strips. The strips are of the type formed from fiberglass reinforced resin pultrusion defining a slot along the inner surface. To prevent the slot opening when the leg is inserted into the hollow interior of the strip, the leg includes a pair of laterally extending projections for engaging the strip in compression fit only at the junctions between the sides and outer edge of the strip.
