Adjustable Spring Power – Sizes 1–6

The 46 Series features a fully adjustable spring, allowing the closing force to be tailored to the specific door and application.

The Size 1–6 adjustment range provides flexibility for use on everything from lighter commercial doors to larger, heavier entrance doors.

Proper adjustment helps provide:

• Reliable closing

• Positive latching

• Improved accessibility

• Controlled door movement

This can help reduce excessive opening force caused by:

• Wind

• Forceful opening

• Shopping carts

• Equipment movement

• Everyday commercial use

Backcheck helps protect the door, frame, closer arm, hinges, and nearby walls from impact damage.

Latch Speed

Controls the final portion of the closing cycle to help ensure the door closes completely and engages the lock or latch.
