A concealed door closer is a type of door closing mechanism that is integrated into the door and frame, making it virtually invisible when the door is closed. Unlike surface-mounted door closers, which are attached to the exterior of the door and frame, concealed door closers are installed within the door or door frame itself, offering a sleek and unobtrusive appearance.

Specifications for a Concealed Door Closer:

• Color: Silver
• Maximum Weight Capacity: 45-65kg
• Maximum Door Angle: 180 degrees
• Passed Durability Cycles: 500,000 cycles
• Applicable Temperature Range: -30°C to 60°C

Concealed door closers are ideal for applications where aesthetics, space, and reduced visibility of hardware are important considerations. They provide reliable performance and contribute to the overall functionality and safety of the building without compromising on design.
