How to shim a Hurd Casement Window –
Using Part # 183 (you can purchase shims from www.RandRwindow.com )
- Crank window all the way open
- locate the sliver hing track screwed into the bottom of the window frame
- loosen the screw that is closet to the corner frame of the window
- Insert shim around the screw (under the hinge track)
- Tighten the screw
- this is a good time to make sure that ALL screws on the hardware are tightened so that the head of the screw is flush (DO NOT over tighten!)
