Abstract: A fenestration installation diagnostic system includes a diagnostic cord and a plurality of diagnostic fittings configured for coupling with a fenestration assembly. Each of the diagnostic fittings includes at least one bracket leg configured to statically couple the diagnostic fitting with the fenestration assembly and at least one alignment interface, and the alignment interface is configured to align the diagnostic cord at a diagnostic intersection.

Abstract: A cable conduit electrical box including a base having at least one opening for receiving a cable conduit, a cover removably attachable to the base, and an adapter removably positioned on the base or the cover for sealing the at least one opening around the cable conduit. The adapter may be secured with mounting tabs or mounting apertures.

Abstract: An electrical outlet cover with a lid having a configurable protrusion or recess to accommodate different uses and weather resistance states. The electrical outlet cover includes a base coupled to an electrical outlet and a lid hingedly coupled to the base along a first side. The lid includes a frame with a central aperture and a telescoping enclosure with a flange at a front edge of a sleeve, the flange extending outward from the sleeve. The sleeve may include a ledge extending outward from the sleeve adjacent a back edge of the sleeve on at least two sides of the sleeve. The sleeve is slidably coupled within the central aperture and movable between an expanded position and a collapsed position. The flange may abut the frame in the collapsed position and the ledge may abut the frame in the expanded position.

Abstract: A electrical box including a top wall, a side wall connected to the top wall, a cavity formed by the top wall and the side wall, at least one mounting flange on the side wall having a mounting hole therein, at least one mounting fastener in communication with the at least one mounting flange, and wherein the mounting fastener is slidably engaged with the at least one mounting flange.

Abstract: In illustrative implementations of this invention, a crucible kiln heats glass such that the glass becomes or remains molten. A nozzle extrudes the molten glass while one or more actuators actuate movements of the nozzle, a build platform or both. A computer controls these movements such that the extruded molten glass is selectively deposited to form a 3D glass object. The selective deposition of molten glass occurs inside an annealing kiln. The annealing kiln anneals the glass after it is extruded. In some cases, the actuators actuate the crucible kiln and nozzle to move in horizontal x, y directions and actuate the build platform to move in a z-direction. In some cases, fluid flows through a cavity or tubes adjacent to the nozzle tip, in order to cool the nozzle tip and thereby reduce the amount of glass that sticks to the nozzle tip.

Abstract: An extendable electrical box comprises an electrical box having two open ends to an internal box space having a first depth. The electrical box comprises a mounting structure attached to at least one wall of the electrical box. The mounting structure is configured to mount the electrical box to a vertical wall structure such that the open end faces substantially parallel to the vertical wall structure. At least two extendable first rings each continuously surround one of the two open ends of the electrical box. The at least two extendable first rings are each slidably coupled with the electrical box via the sliding mechanical cooperation of one or more guides with one or more tracks, such that sliding either of the at least two extendable first rings in relation to the open ends of the electrical box expands the electrical box from the first depth to a larger second depth.
