Product Q&A
Q:What door sizes and weights is the DS-051 compatible with?
A:
The DS-051 is rated for door leaves up to 700mm wide and 25-45kg in weight, covering standard residential interior doors, light commercial doors, and most fire door applications in this size range.
Q:Is the DS-051 suitable for fire doors?
A:
Yes. The DS-051 is designed for fire door applications. Its consistent hydraulic closing force ensures the door returns fully to the closed and latched position every cycle, maintaining the integrity of fire compartmentation as required by building codes.
Q:Can the closing speed be adjusted after installation?
A:
Yes. The DS-051 features two independent speed adjustment valves - one for the main closing sweep and one for the final latch zone. Both can be adjusted by rotating the valve screws on the body without removing the unit from the door.
Q:Does the DS-051 support a hold-open function?
A:
Yes. The positioning function is optional - the unit can be configured to hold the door open at a fixed angle or set to close freely without a hold-open stop, depending on the installation requirement.
Q:What is your minimum order quantity for door closers?
A:
Our minimum order quantity is 1 piece, and sample orders are acceptable for quality testing.
