Heavy Duty Door Closer with 90 Degree Hold-Open

This hydraulic door closer is engineered for stable motion control on single swing doors where controlled closing and reliable positioning are required. The internal hydraulic structure delivers consistent resistance throughout the door travel, helping reduce impact stress on frames and improving long-term operating stability.

A built-in 90 degree positioning function allows the door to remain open when needed, while the system supports automatic hydraulic closing up to 180 degrees. Two-stage speed adjustment enables precise control of both sweep and latch phases, allowing the closing performance to be tuned according to door size, weight, and site conditions.

Designed for wide door applications, this closer supports left- and right-hand installation without structural modification, making it suitable for commercial buildings, public facilities, and specification-driven hardware projects.

• Integrated hydraulic control provides stable resistance throughout the opening cycle, helping reduce impact force and frame wear in daily operation.
• Fixed positioning at approximately 90 degrees allows doors to remain open when required, improving traffic flow during peak usage periods.
• Dual speed regulation enables independent tuning of sweep and latch zones, supporting precise adjustment for different door weights and site conditions.
• Extended arm geometry supports wider single swing doors, making the unit suitable for commercial entrances and public access points.
• Universal handing design allows installation on left or right opening doors without component changes, simplifying inventory and replacement work.
• Sealed hydraulic structure is designed for long-term operation across a wide temperature range, supporting consistent performance in varied environments.
