Hydraulic Door Closers & Arms for Safety

A door arm works by linking the hydraulic closer body to the door frame. As the door opens, the arm tensions the hydraulic cylinder. When released, pressurized hydraulic fluid inside the cylinder is metered through internal valves, creating controlled resistance that guides the door back to its closed position at a regulated speed, preventing abrupt impact.

A hydraulic door refers to a door fitted with a hydraulic closing mechanism — a gas-loaded or fluid-filled cylinder that controls the speed and force of the door's closure. Hydraulic doors are widely used in walk-in coolers, freezers, and commercial kitchens where self-closing is required for safety, energy efficiency, and sanitation compliance.

The Kason 1094 SureClose hydraulic door closer is life-cycle tested to reliably operate after 500,000+ closures. This rigorous testing ensures consistent performance in heavy-use commercial environments such as restaurants, grocery stores, and industrial refrigeration facilities, significantly reducing the need for frequent replacements or maintenance.

The 1094 is a standard hydraulic door closer providing consistent controlled closure. The 1094S is a Dual-Speed variant that features a snubbing mechanism offering an initial fast closure followed by a secondary slow-close action near the final position, minimizing impact and reducing stress on the door frame and seals.

Yes, the Kason 1094 SureClose hydraulic door closers are specifically rated for cooler and freezer temperature applications. Their heavy-gauge steel construction and gas-loaded hydraulic cylinder are engineered to maintain reliable performance in cold storage environments, making them suitable for walk-in coolers, walk-in freezers, and commercial refrigeration units.

The Kason 1094 SureClose is available in both exposed and concealed mounting models, offering installation flexibility to suit different door configurations. Mounting holes are pre-drilled for No. 10 (5.0 mm) screws, which are included. The extra-wide hook features mounting slots for easy alignment adjustment during installation.
