The closer is non-handed, making it suitable for right- or left-hand doors and adaptable for regular arm, top jamb, and parallel arm applications.
Engineered to meet barrier-free requirements, the adjustable spring power range from Size 1–6 allows for precise door control to comply with ADA and ANSI accessibility guidelines. An adjustable backcheck controls opening motion during abusive or abrupt door swings, helping protect walls, frames, and hardware.
