A collapsible cable regulator assembly is provided, having a collapsible support structure wherein one or more swing arms are pivotably mounted to a lateral member. Cable guide means are provided for mounting a regulator cable, including a cable return at the free end of each of the swing arms. The collapsible support structure is openable from a collapsed condition in which each swing arm is at an acute angle to the lateral member, to an operating condition in which each swing arm is at an operating angle to the lateral member which is greater than the aforesaid acute angle. The cable regulator assembly in its collapsed condition has improved installation capability, being especially advantageous for installation through limited access openings. Once in proper location, the cable regulator assembly is opened to its operating condition. The regulator assembly can then be permanently or non-permanently mounted in position, and a windowpane or other moveable member attached to mounting brackets or gliders driven by the regulator cable. In the operating position the swing arms act as guide rails with good parallelism aided by the lateral member acting as an interconnecting cross-member between the guide rails.
