Two side-by-side housings each receive a telescoping member therein. Bearings captivated within each housing engage the telescoping members such that the bearings are free to slide both with respect to the housings and the telescoping members. A handle for operating the lever and an arm for engaging the car coupler are mounted to opposing distal ends of the telescoping members. The other ends of the telescoping members are free to extend beyond the housings and have stops which abut the bearings while these ends are disposed within the housings.
