Material & Finish: The core components are made of heavy-duty die-cast aluminum or zinc alloy with a textured matte silver/gray anti-corrosion finish.
Main Casing Casing (Top-Right): A vertical mounting body containing internal springs and hydraulic/silicone oil damping mechanisms to handle the kinetic energy of heavy doors. It features pre-drilled mounting holes at the base.
Articulated Lever Arm (Left): A long, solid metal pivoting linkage bar that transfers the closing motion from the door frame to the damper body.
Adjustable Linkage Rod (Center): A central threaded connecting rod attached to a clevis pin and screw joint at the top. The threaded lower end connects to a jointed pivot foot, allowing installers to adjust the tension, length, and closing speed.
