HAHN marketed the doorstop to prevent open porch doors, screen doors as well as house and room doors from slamming shut during intermittent or cross ventilation. The doorstop reliably keeps the door open and ensures safe and proper ventilation.
Special doorstops from HAHN prevent doors from slamming during inclement weather. To keep your door wide open, the doorstop can be locked in any position. The HAHN doorstop comes in various models and is available in high-quality, weather-resistant stainless steel.
