This restrictor limits door opening to a preset position, or to a maximum of 90 degrees, and includes an easy-to-fit eurogroove and bracket to frame. Our Door Stay is perfectly suitable for all major uPVC profiles, and measures 335mm in length. It can withstand literally thousands upon thousands of openings without becoming damaged, and does not become affected by daily wear and tear. Additionally, a carefully constructed slider contains special friction screws to hold the door open in mild wind conditions, so that it remains stable and steady.
