Import Concealed Door Closer — Buy in Bulk from Supplier in Thailand

The concealed overhead door closer from Winner Door Hardwares Co., Ltd. is a double-action mechanism designed for wooden, metal, aluminium, and toughened glass doors. It operates with a maximum opening angle of 105 degrees in each direction, allowing doors to swing both inward and outward while maintaining controlled closure. The closer is engineered to handle doors up to 1,200 mm in width and weighing as much as 100 kg, making it suitable for heavy-duty applications.

This model is supplied in cartons with a gross weight of 26.7 kg and dimensions of 36x59x11 cm, which is typical for bulk shipments of door hardware. The concealed design ensures the closer is hidden within the door frame or head jamb, preserving the door’s aesthetic while providing reliable closing force. The mechanism typically includes adjustable closing speed and latch speed, standard features for customizing performance to the door’s weight and usage frequency.

Contractors and facility managers specify this closer for commercial buildings, hospitals, and schools where durability and smooth operation are critical. The double-action functionality is particularly useful in high-traffic areas where doors must swing in both directions. Buyers should confirm the exact closing force (measured in EN or ANSI standards) and the compatibility with their door’s material and thickness before ordering.
