Abstract: A system for mounting a relatively thick multiple glazed sealed unit to a wooden sash assembly of a standard thickness. The system comprises a peripheral base member inserted between the glazed unit and the sash of the window and a retaining moulding engaged to the peripheral base member and pressing the glazed unit in the sash to hold it in place. A suitable weather strip is applied between the glazed unit and the retaining moulding to prevent air infiltration.

Abstract: An improved shoring frame adapted by a unique design to utilize relatively thin-walled aluminum tubing with a reasonable load-rating, be easily manufactured, and be compatible with existing steel accessories; where the extruded aluminum legs are each generally circular with a longitudinally-extending flattened portion for attaching struts and studs, and preferably having at least two internal ribs, circumferentially symmetrically-spaced relative to said flattened portion axially to contain accessories such as existing jack screws, extension legs, U-head fixtures, and the like.
