Abstract
A casement window lock and tie bar assembly including a flexible guide pre-formed with an arcuate deflection. The guide receives a tie bar having a c-shaped cross-section. The arcuate deflection of the guide causes the guide to be frictionally held in an initial position on the longitudinal axis of tie bar. When fasteners are tightened to attach the guide to a window frame, the guide is flattened to enable the tie bar to freely slide on the guide.
