What Is the King Door Closer 70 Series?

The King Door Closer 70 Series is a surface-mounted hydraulic door control device. It uses a rack-and-pinion mechanism to regulate the door’s movement during opening and closing. Adjustable hydraulic valves allow installers to control the main closing speed and final latching action.

The King Door Closer 70 Series product specifications describe its aluminium alloy construction, adjustable closing controls, and suitability for residential and medium-to-heavy commercial applications. The appropriate model should be selected according to the door’s weight and width.

Why Choose the King Door Closer 70 Series?

Smooth and Controlled Door Closing

The hydraulic mechanism controls the door’s movement instead of allowing it to swing shut freely. This helps reduce slamming and supports a more comfortable environment. It is especially useful in offices, corridors, shops, and other areas with frequent foot traffic.

Adjustable Closing and Latching Speeds

Separate adjustment valves allow installers to regulate the main closing movement and final latching action. Correct adjustment helps the door close smoothly while still engaging its latch. Settings should suit the door’s weight, hinges, and operating environment.

Durable Aluminium Alloy Construction

The aluminium alloy housing protects the internal hydraulic components during regular use. Steel components within the mechanism support controlled movement and durability. Proper installation and periodic inspection help maintain reliable operation over time.

Flexible Left-Hand and Right-Hand Installation

The non-handed design supports installation on suitable doors that open in either direction. This makes the closer useful for different building layouts and replacement projects. Correct mounting positions and arm arrangements remain essential for proper operation.

Multiple Door Power Sizes

The referenced 70 Series configuration includes different power sizes for varying door weights and widths. Size 2 suits doors up to approximately 40kg, while Size 3 supports up to 60kg. Size 4 supports doors up to approximately 80kg, subject to installation conditions.

Selecting the correct size helps provide effective closing without unnecessary resistance. For heavier or wider doors, verify the manufacturer’s recommendations before installation.

Common Applications

The King Door Closer 70 Series suits a variety of everyday building requirements:

• Offices: Helps doors close automatically between meetings and work activities.

• Retail shops: Supports controlled closing on entrances and internal doors.

• Schools: Helps manage frequently used classroom and corridor doors.

• Hotels: Supports convenient door operation in suitable rooms and service areas.

• Apartment buildings: Helps keep common-area doors closed after use.

• Commercial premises: Supports orderly access through staff rooms and internal entrances.

Installation and Maintenance

Install the door closer using the correct mounting template and supplied hardware. Ensure the door, frame, hinges, and arm can support the selected closer. Adjust the sweep and latching valves gradually, following the manufacturer’s instructions.

Avoid loosening adjustment valves excessively, as this may cause hydraulic fluid leakage. Inspect mounting screws and the arm periodically, especially on doors used frequently. For installation guidance and configuration details, consult the King 70 Series product reference.
