Adjustable Hidden Pivot Hinge Commercial Door Closer in Stainless Steel & Silver by Oukaning

Robust and Long-lasting: Crafted from stainless steel and aluminum alloy, with a wire drawing process, it's resistant to wear, corrosion, deformation, and rust, ensuring a durable lifespan. High Strength Bearing: Stainless steel bearings and a carburized, heat-treated center shaft offer superior strength and durability, supporting up to 165 lbs and preventing door sagging. Dual Adjustable Speeds: Two speeds can be adjusted (closing speed of 150-10° and locking speed of 10-0°) to cater to various closing needs, with the door self-closing and stopping at 90°. Quiet Operation: The silent spring, built-in pressure-reducing valve, and hydraulic buffer designs enable smooth, quiet door closure without disturbing your environment. Excellent Sealing: A high-quality rubber sealing ring with strong toughness effectively prevents oil leakage and protects internal door components from wear and damage upon closure.
