Casement friction stays are crucial components of casement windows, responsible for maintaining proper alignment and smooth operation. Ensuring their proper alignment is essential for optimal window performance and longevity. This article will delve into the key aspects of aligning casement friction stays effectively.

Understanding Casement Friction Stays

Casement friction stays are devices installed on casement windows to hold the window sash in place when open. They consist of a friction shoe that slides along a track, providing resistance to the sash’s movement. Proper alignment ensures the friction shoe engages evenly with the track, ensuring smooth and controlled opening and closing.

Steps for Proper Alignment


Identification of Adjustment Points

Locate the adjustment screws or bolts on the casement friction stay. These are typically found at the end of the friction shoe or near the track.


Adjusting Vertical Alignment

Use a wrench or screwdriver to adjust the vertical screws. Turn the screws in small increments until the friction shoe is aligned with the center of the track. Ensure the shoe glides smoothly along the track without any binding or catching.


Adjusting Lateral Alignment

Adjust the lateral screws to align the friction shoe within the track’s width. Lateral alignment ensures the shoe engages evenly with both sides of the track, providing balanced friction and preventing the sash from rubbing against the frame.


Checking and Refinement

Open and close the window several times to check the alignment. Make minor adjustments as necessary until the sash moves smoothly and stays in place when open. Ensure there is no excessive friction or play in the system.

Additional Tips

Regular Inspection and Maintenance

Regularly inspect the casement friction stays for any signs of wear or damage. Clean the track and friction shoe with a soft brush to remove dirt and debris.


Apply a light coating of dry lubricant to the track and friction shoe to reduce friction and improve operation. Do not over-lubricate, as this can attract dust and debris.


If the friction stays are worn or damaged beyond repair, replace them promptly to avoid window failure. Use high-quality stays that are compatible with the window’s design.
