Slim uPVC Window Trickle Vents for Quiet Airflow

Usage Tips

• For best performance, install on the upper part of the uPVC window sash
• Slot or drill guides should match the vent’s airflow opening
• Ensure the sliding flap opens smoothly before final installation
• Do not over-tighten screws to avoid damage to plastic housing
• Avoid installing in non-uPVC frames, as fit and performance may vary
