ABSTRACT:
A movable door mounting assembly includes a stud assembly and a trolley assembly having a spring-biased cam piece that pivots between a normal position, which allows the trolley assembly to move freely on the track, and a locked position, which causes a locking surface on the cam piece to frictionally engage with a top surface of the track and hold the trolley assembly in place while the door is being hung. A catch in the stud assembly engages with the cam piece when the mounting assembly is fully assembled. Inserting the stud assembly into the trolley assembly, releases the cam piece from its locked position and, at the same time, positions the catch so that it engages with the cam piece when the door is hung.
