An air handling grille with an open rectangular frame which defines two opposing grooves each bounded by a narrow flange. A series of adjustable vanes each with opposite bearing studs is preassembled with elongated resilient bearing members. Each bearing member has a series of small openings to hold the bearing studs. The bearing members are mounted on the studs during preassembly and the members are thus entered in the grooves. Each member includes a flange which is deflected inwardly during assembly and thereafter latches the bearing members in assembled position. The flanges also tend to twist the bearing members restricting bearing openings therein and frictionally retaining the studs. A second series of vanes is supported by a pair of cross members. Spring clips secure the vanes on engagement with ends of the cross members. |
