1. A method of making a multi-point window locking mechanism tie bar, comprising:
cutting a section of flexible and resilient polymer material from a roll, the section having a predetermined length;
punching a plurality of spaced-apart apertures in the section along a longitudinal axis of the section;
cutting a first notch in the section along the longitudinal axis of the section at a location between the spaced-apart apertures, the first notch adapted to receive a saddle, the saddle having either a projecting locking point or a projecting drive pin; and
providing a track having a c-shaped cross-section, and slidably engaging the saddle in the track, the track adapted to be secured to a window frame by inserting fasteners through the plurality of spaced-apart apertures in the tie bar.
