Commercial Door Closer Replacement Arm | Mechanical Friction Hold Open | For Prime 46 Series Closers

Add convenient mechanical hold-open capability to a compatible Prime Door Controls 46 Series commercial door closer with the 46 Series Friction Hold Open Arm.

Designed for commercial openings where the door periodically needs to remain open, this replacement arm uses an adjustable friction mechanism to hold the door at an open position until the user manually releases the hold.

It is an excellent accessory for commercial, institutional, retail, warehouse, and service-door applications where temporary hold-open operation is useful.

Key Features

• Designed for compatible Prime Door Controls 46 Series closers

• Friction Hold Open (FHO) Arm

• Mechanical hold-open operation

• Holds compatible doors in an open position

• Releases when the door is manually pulled or pushed from the hold-open position

• Commercial-grade closer accessory

• Ideal for high-traffic commercial openings

• Suitable for replacement and retrofit applications

• Helps eliminate the need for a separate floor or wall-mounted door holder

• Replacement arm only

• Designed for non-fire-rated hold-open applications

Friction Hold Open Operation

The arm uses mechanical friction to maintain the door in an open position.

When the door is opened to the hold-open range, the friction mechanism helps keep it in position. Applying sufficient force to the door releases the hold so the closer can return the door to the closed position.

Friction hold-open arms are commonly used where doors periodically need to stay open for:

• Deliveries

• Cart traffic

• Equipment movement

• Cleaning

• Maintenance

• Moving furniture

• Stockroom access

• Temporary high-volume pedestrian traffic

Commercial Replacement Arm

This arm is an excellent replacement when the existing closer arm is:

• Bent

• Broken

• Worn

• Loose

• Missing

• No longer holding the door open properly

• Damaged from repeated commercial use

• Being upgraded from a compatible non-hold-open arm

When replacing the arm, inspect the closer spindle, arm shoe, mounting points, and closer body for additional wear or damage.

Mounting Applications

Depending on the compatible bracket and mounting hardware, friction hold-open arms are commonly used in:

• Regular arm installations

• Top jamb installations

• Parallel arm installations

For parallel-arm installations, a compatible parallel arm bracket may be required.

Always verify the complete 46 Series mounting configuration before ordering.

Important Fire Door Note

A mechanical friction hold-open arm should not be used to hold open a fire-rated or smoke-control door when doing so prevents the door from performing its required self-closing function.

Where a rated opening requires hold-open capability, use an appropriately listed automatic-release system designed for the application.
