Abstract: A system utilizing multiple spacer and shim elements that nest together to raise a closet ring to the height required for the particular floor being used in a given application for a toilet bowl installation. The nested spacer and shim elements are placed on the rough floor and receive the closet ring mounting flange. Bosses on an upper side of a lower spacer and shim element are received in detents in a lower side of a corresponding upper spacer and shim element so that the spacer and shim elements are held securely in their nested position so as to form a registered spacer/shim stack. The spacer and shim elements will typically be ¼″ thick. The spacer and shim elements further include breakaway mounting tabs positioned about an outer circumference of the main body of the spacer and shim elements.

Abstract: This apparatus for etching designs in a substrate, such as a glass door or window, has a transparent casing having an opening to be positioned against the substrate. A manually directable sandblasting nozzle is positioned inside the casing. A device is also provided for delivering a stream of compressed air containing sandblasting grit particles to the nozzle. The transparent casing is designed to be hand-held. In use, the substrate is masked except where the pattern is to be etched, and the transparent casing is positioned against the substrate. Sandblasting in the area of the substrate covered by the casing is carried out, and the casing moved to remaining areas of the substrate for further sandblasting until the complete design is formed in the substrate. This apparatus allows attractive designs to be formed in glass doors and windows without removing the glass from its installation.
