USCAN 4000 Series Grade 1 Closers

Master high-traffic entryways with the USCAN 4000 Series Grade 1 Heavy Duty Door Closer. Engineered for rugged institutional, architectural, and busy commercial environments, this surface-mounted multi-power closer delivers maximum durability and smooth operational control under continuous use.

Key Features

• Heavy-Duty Construction: Built with a precision cast aluminum alloy housing and a robust hydraulic rack-and-pinion mechanism to withstand the abuse of severe high-traffic storefronts.

• Fully Adjustable Power (Sizes 1–6): Seamlessly adjusts spring tension from sizes 1 to 6 to handle everything from light barrier-free interior doors to heavy exterior building perimeters.

• Complete Hydraulic Customization: Features three independent, non-critical thermostatic valves controlling sweep speed, latching speed, and adjustable cushioning backcheck to prevent the door from catching the wind and slamming back.

• All-Weather Reliability: Formulated with premium non-gumming and non-freezing hydraulic fluid to guarantee steady closing control across radical temperature shifts.

• Versatile Tri-Pack Mounting: Ships standard with hardware for regular, top jamb, or parallel arm layouts, making it highly adaptable on-site.
