Corner members and frame members forming an assembly is provided, for holding a screen or the like, in which the corner members have arms disposed to be connected to frame members, preferably by being telescopically received therein, for facilitating retaining the frame assembly, which is a removable assembly, inside a fixed frame of a window. Upper corner members of a moveable frame have a U-shaped attachment means formed by an upwardly projecting flange and tab forming U-shaped channels. The top of the frame having the U-shaped attachment means is inserted at an angle into a downwardly projecting lip means on a fixed frame such that the U-shaped attachment means loosely embraces the lip means. The moveable frame is rotated until the U-shaped attachment means fully embraces the lip means, the moveable frame is flush with fixed frame, and the moveable frame is locked into position against the fixed frame with retaining mechanisms on the remaining two corners of the moveable frame.

A frame assembly for doors, windows and the like includes a fastening element consisting of a longitudinal connecting portion and a transverse clamping portion, a first frame provided with a plurality of locking holes and a second frame provided with two fastening holes. The connecting portion has a side plate extending substantially perpendicular to either lateral side thereof and is provided with a plurality of threaded holes at an upper portion thereof for matching the locking holes. The clamping portion consists of a clamp plate punched and bent from a middle portion of the connecting portion and a grip plate in a relative clamping relationship with the clamp plate; the grip plate being provided with two projecting hook pieces for matching the fastening holes. The connecting portion may be inserted into the first frame so that they may be locked firmly and conveniently by screws. The clamping portion is fitted onto a rear side of the second frame such that the hook pieces of the grip plate hook against the fastening holes in the second frame to ensure the assembly.

A method and apparatus for effecting changes of direction in cable trays constructed of fiberglass include structural members having ends at a 90.degree. angle at (A) which are supplied with splice plates including corner members (B) presenting converging sides (C). The corner members have web members (D) extending therefrom at an angle complementary to the angle in which a change of direction to be effected at the joint wherein the splice plate is utilized.

The window buck is made of extruded irregular shapes consisting of a combination of cellulose and polymer compounded specifically to be used in connection with building walls of poured concrete. The combination desirably is a mixture of approximately 70% cellulose and approximately 30% polymer. The cellulose is preferably sawdust, and the polymer preferably is polyethylene.

A refrigerator cabinet has an outer case with lateral walls and a continuous front flange. A pair of liners are nested in the case and have lateral walls with a front edge positioned rearward of the case front flange. A resilient breaker strip connects the case walls to corresponding liner walls. The strip front wall extends inward from the case flange to a point inward of the liner wall and a side wall extends rearward to overlap the liner wall. A bifurcated edge of the strip receives the case flange. The strip side wall is return bent to form an inner wall engaging the inner surface and a resilient finger engaging the outer surface of the liner wall. A resilient mullion, connecting the adjacent inner lateral walls of the liners, has a front wall extending across the space between the liners and a side wall projecting rearward from each edge of the front wall to overlap the liner lateral wall. Each mullion side wall is return bent to form an inner wall engaging the inner surface and a resilient finger engaging the outer surface of the liner wall.
