ABSTRACT:
End plastic connectors on the ends of two construction members like concrete forms. Each connector has a pair of bosses on opposite corners and a pair of openings in opposite corners so that the bosses on one connector mate with the openings in the other connector. Each boss has an annular rib sized to press through the associated opening, which is circular with a pair of flats, to latch the connectors together. Each rib is spaced from the remainder of the associated connector a greater distance than the thickness of the material of the connectors around the openings thereby permitting limited angular adjustment in orientation between connectors. Each construction member is a piece of dimensional lumber in one form of the invention, to which the end connectors are attached by nailing. In the other form of the invention, each construction member is a plastic extrusion and the end connectors have protrusions interfitting into the plastic extrusion. The wall of the extrusion at one side is shaped into a lipped dove-tailed keyway extending from end to end of the extrusion. A locking cam secures a stake to the construction member. The clamp has a rectangular base that fits into the keyway and locks therein by turning. The plastics are formed of polyethylene, which has a release agent, and which has an ultraviolet stabilizer. Extrusions contain titanium dioxide pigmentation for maximum sun ray reflection to reduce extrusion flexibility by heating.
