The edging strip stiffens and reinforces the glass, allowing the use of thinner glass sheets and provides a convenient means for attaching the sheets together at corners.

Abstract: A pulley guard for a slidable fence gate having elongated horizontal rods supported on a plurality of pulleys rotatably mounted on fixed horizontal stub shafts, comprises a housing surrounding the pulley and preventing inadvertant finger access to the periphery of the pulley. Appropriate notches are provided in the walls of the housing to provide clearance for the stub shaft and for the elongated horizontal gate rod with which the pulley cooperates.

Abstract: A one-piece sealed, hollow, steel sliding screen door frame and method of fabrication thereof is described. A flat steel strip is diecut to produce 45.degree. miter cuts, each having an opposing flap. The cut strip is rolled to produce a frame stock having an essentially rectangular profile. Longitudinal edges of the strip are folded together, crimped and bonded during the rolling and form a screen channel in the frame stock. The frame stock is bent at right angles at the miter cuts such that the flaps tuck under the miter cuts, forming a rectangular door frame. Epoxy is used to bond the flaps to the inner surfaces adjacent the miter cuts. A screen door assembled using the door frame includes self-centering wheel assemblies.
