- The new type is B-874-1. The torque curve differs from that of the old type B-874.
- The rotary reaction force is so strong that the product can be applied to the opening and closing mechanism for various kind of doors.
- Adjustment can be made to an optimum torque according to the weight of the door.
- Because the product is not the stay type like the gas spring, it requires less space for installation.
- Adjust the screw plug allowing it to project from 9 to 12mm.
