5. Installation Steps

1. Prepare Door & Frame: Ensure door width (≤950mm) and weight (40–65kg) match DDDC027BC specifications. Gather tools (drill, screwdriver, measuring tape).
2. Select Installation Type: Choose standard, top-jamb, or parallel arm setup based on door/frame design and door hinge configuration.
3. Mount Aluminum Alloy Closer Body: Attach the durable aluminum alloy closer body to the door or frame, aligning with door lock and door hinge positions for optimal operation.
4. Install Arm & Linkage: Connect the closer arm to the door and closer body, adjusting linkage for proper door travel and Back Check functionality.
5. Adjust Closing, Latching, & Back Check: Use hydraulic controls to calibrate closing and latching speed, and verify Back Check operates to prevent overly fast door opening.
6. Verify Operation & Integration: Test door closing/latching and Back Check performance, ensuring compatibility with panic exit devices, door stops, and other door accessories.

6. Application Scenarios

The DDDC027BC Aluminum Alloy Hydraulic Door Closer excels in environments requiring fire safety, durability, and adjustable performance, including:

In hotels, the aluminum alloy construction ensures durability in lobbies while Back Check protects guest room doors from slamming, integrating with door locks for security. For offices, UL fire rating meets safety codes for corridor doors, pairing with concealed hinges for a sleek look. In hospitals, hydraulic adjustable speed enables quiet closing in exam rooms, while Back Check prevents abrupt openings, matching stainless steel door stops and door handles for hygiene and safety.
