Abstract
A guide assembly or balance shoe assembly for slidably and pivotably mounting a window sash to a window jamb is disclosed. The guide assembly includes a shoe housing having sliding surfaces that guide the housing in the jamb channel. A sash pivot is coupled to the window sash and a locking cam is rotatably coupled within the shoe housing. The locking cam includes a sash pivot that retains the sash pivot pin. The locking cam rotates substantially with the sash pivot and the locking cam has a locking surface that is configured to engage the jamb channel when the sash pivot is rotated to a first position.
