Door Operator Arms

Key Features

• Multiple arm types, including standard (regular), track/slide, long/telescoping, and parallel arms to match specific operator models and door/frame geometries.
• Non-handed or reversible designs that work for left-hand or right-hand doors, simplifying inventory and field adjustments.
• Heavy-duty construction typically in aluminum-painted (689), anodized (628), or steel finishes for corrosion resistance and long-term durability.
• Compatible with low-energy operators (e.g., LCN 9540, Falcon 8200) and electrohydraulic closers (e.g., LCN 4640), supporting ADA-compliant speeds and forces.
• Integrated track and roller systems on slide/track arms for reduced projection and smoother operation in tight reveal conditions.

Key Benefits

• Optimized door performance by matching arm geometry to the operator, door weight, and swing reveal for consistent opening/closing cycles.
• Improved accessibility with arms designed for low-energy operation that meet ADA force and speed requirements while maintaining safety.
• Easier installation and maintenance through standardized part numbers, reversible mounting, and direct compatibility with popular operator series.
• Extended operator life by properly distributing mechanical loads, reducing stress on motors, gears, and hydraulic components.
• Flexible retrofits allowing arm upgrades or replacements without changing the operator head, minimizing downtime on existing automatic doors.

Applications

• Healthcare and assisted living facilities where low-energy operators on patient room or corridor doors need precise arm control for gentle operation.
• Commercial offices and retail entrances requiring track or standard arms for push-side surface-mounted low-energy operators.
• Schools and public buildings with electrohydraulic closers using long arms to accommodate deeper reveals or heavier doors.
• Multifamily and hospitality common areas where replacement arms restore automatic function to aging low-energy door systems.
