DDFS500 — Heavy Duty Hydraulic Concealed Floor Spring Door Closer with 90° Hold Open
D&D DDFS500 is a heavy-duty hydraulic concealed floor spring designed for controlled closing of commercial wooden and metal doors. Installed below the door, its compact metal body remains largely concealed to maintain a clean entrance appearance. The floor spring supports doors from 800 to 1200 mm wide and covers a door-weight range of 60–500 kg, making it suitable for large and heavy entrance doors. It provides single-speed hydraulic adjustment, controlled closing and latching action, a 90° hold-open position and a maximum opening angle of 125°. With a working life of at least 500,000 cycles and an operating temperature range from -20°C to 50°C, DDFS500 suits hotels, offices, shopping centers, public buildings and other high-use commercial entrances.
