CA 2364823

An improved casement window is provided which includes a tie bar and at least two tie bar guides through which the tie bar slidably extends. The tie bar guides are secured to a window frame which includes an elongated groove that extends parallel to the tie bar. Each tie bar guide includes at least one locating leg that extends outward from the tie bar guide body and that is received in the groove of the window frame to assist in the easy location of the tie bar guide and tie bar along the window frame. Further, each tie bar guide may be equipped with a protruding nib that is received in an aperture disposed in the tie bar. The cooperation of the tie bar guide and the aperture of the tie bar ensures that the tie bar guide is properly spaced along the length of the tie bar. The nib is sheared off of the tie bar guide after the tie bar guide is secured to the window frame and the tie bar is moved axially through the guide. The tie bar guide may also include outwardly protruding ribs that provide structural support for the wood stop that overlays the tie bar, the tie bar guides and the window frame. Distal ends of the back wall of the tie bar guides may be tapered and supported by a ledge. 'The length of the tapered distal ends may be shortened to adjust the position of the tie bar guides with respect to the window frame. The roller of the tie bar may be eccentrically mounted to enable the position of the roller to be adjusted after the tie bar and tie bar guides are secured to the frame. An improved keeper is provided which can be more securely attached to the sash to prevent pull-out.
