Import Door Closer B-961 — Buy in Bulk from Supplier in China

The Door closer B-961 is a hydraulic door control device designed for medium to heavy-duty applications, with a maximum door width of 950mm and a maximum door weight capacity of 60kg. It features a fully hydraulic system with two independent speed control valves that allow precise adjustment of both the opening buffer and closing speed. The body is constructed from aluminum alloy with electrostatic paint finish, and the internal spring is engineered for high torque output, ensuring consistent performance across repeated cycles. The unit supports a 180-degree maximum opening angle and includes a side swing rocker for simplified installation.

The closer uses an imported gasket to prevent oil leakage and incorporates a reinforced spring mechanism rated for over 500,000 cycles without degradation. The aluminum alloy housing is coated with two protective bright finishes to resist corrosion and abrasion. Standard applications include plastic steel doors, wood doors, aluminum doors, and iron doors. The closing force is adjustable via the position of the supporting arm, and the locking segment is set to hold the door securely at full open. Typical industry standards for such devices require a minimum of 200,000 cycles for commercial use; this model exceeds that with its 500,000-cycle rating.

Buyers in the construction and architectural hardware sectors commonly specify this model for public buildings, hotels, and commercial entrances where durability and silent operation are critical. The product is typically shipped in bulk packaging of 20 units per carton, with each unit individually wrapped for protection. Trade terms are FOB from Guangzhou port, and lead time is confirmed upon order placement. Minimum order quantities are not stated in the listing and must be verified directly with the supplier.
