Abstract
Guide rails for a cantilevered elevator are mounted in the elevator hoistway on structural components of the building. The mounting assembly provides for an increased number of guide rail securement points in the hoistway without the need for increasing the number of structural components directly built into the building. Increased resistance to lateral deflection of the guide rails is thus achieved without requiring heavier than normal guide rails.
