An elevator guide rail block assembly configured for use with an elevator car or counterweight guide rail is provided. The elevator guide rail block assembly includes a framework and a plurality of cams supported for rotation by the framework and positioned between spaced apart support elements. The spaced apart support elements are connected together by a retention element. An actuator element is configured to actuate rotation of the plurality of rotatable cams. A clamp structure is attached to the framework and is spaced apart from the plurality of rotatable cams. In a rotated orientation, each of the plurality of rotatable cams engage a face of an elevator or counterweight guide rail and the clamp structure engages an opposing face of the elevator or counterweight guide rail to form a clamping action configured to secure the elevator guide rail block assembly to the elevator car or counterweight guide rail.
