Adjustable Spring Power – Size 1 Through 6

The 46 Series features adjustable spring power that allows the installer to tailor closing force to the door and application.

Spring Range: Size 1–6

This broad adjustment range makes the closer suitable for many commercial door sizes and operating conditions.

Proper adjustment should take into account:

• Door width

• Door weight

• Interior versus exterior location

• Wind and stack pressure

• Latching requirements

• Accessibility requirements

Backcheck Control

Integrated backcheck helps cushion the door as it approaches the fully open position.

This can help reduce:

• Door impact against walls

• Stress on hinges

• Damage to door hardware

• Sudden opening caused by wind or heavy traffic

Backcheck is intended to control opening speed and is not a substitute for a mechanical door stop where one is required.

Controlled Self-Closing

The 46 Series provides reliable hydraulic door control to help ensure the opening closes after use.

A properly adjusted closer can help:

• Maintain building security

• Reduce conditioned-air loss

• Control door movement

• Improve latching consistency

• Protect the door and frame

• Maintain proper operation on frequently used entrances

Accessibility Applications

The adjustable spring-power design allows the closer to be configured for accessibility-related openings when the complete door assembly, opening force, closing speed, hardware, and installation meet applicable requirements.

Final ADA and code compliance depends on the complete installed opening and field adjustment.

• Door width and weight

• Door and frame construction

• Mounting configuration
