Abstract
A window sash support and movement lock assembly reciprocably disposed within an associated track element. The sash support and movement lock assembly includes a body with a center opening and guide surfaces on each end. A cam unit is received in the center opening and, upon cam rotation caused by tilting of an associated window sash, the guide surfaces are biased apart and into snug engagement with parts of the track element; one part of one of the guide surfaces also carries one or more pins which then engage an end wall of the track unit to provide a secure locking action.
