ABSTRACT:
A pivot shoe which slides in a track includes a body which receives a cam. The cam is rotated by a sash pivot shaft for engagement of a wall of the track by the shoe for resisting movement along the track when the sash is rotated on the shaft to a position generally perpendicular to the track. The cam defines a first axial opening for receiving the shaft, and defines a second radial opening for removing the shaft from the cam. The body defines a third radial opening which is in alignment with the second opening when the sash is rotated to the track engaging position. A reversible obstructor for the second opening provides for easy installation or removal of the shaft from the shoe.
