A truss joist includes an upper chord, a lower chord and a series of links. The series of links connects the upper and lower chord and terminates in an end link which is attached to the lower chord and extends upwardly toward the terminal portion of the upper chord. An end bracket which partially surrounds the terminal portion of the upper chord includes a U-shaped channel which contacts the side and bottom surfaces of the upper chord. The U-shaped channel further comprises a pair of downwardly projecting legs for connectively receiving the flattened end portion of the end link. One embodiment of the end bracket lies directly upon the upper surface of a support member. Another embodiment is flush-mounted against the inner surface of the support member and has a horizontal flange which extends over the upper surface of the support member. Additional embodiments of the end bracket include adjustable bracket elements mounted below the U-shaped channel and on either side of the downwardly projecting legs. Since those adjustable end brackets are slidably connected to the end bracket, they allow the length of the truss joist to be adjusted. These adjustable bracket elements include flat end surfaces which permit them to be nailed to the inner surface of the support member and thereby assist in securing the end bracket to the support member.
