Friction Hold Open Application

The bracket is intended for use with a compatible 46 Series Friction Hold Open Arm.

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

Common uses include temporarily holding doors open for:

• Deliveries

• Cart traffic

• Equipment movement

• Cleaning

• Maintenance

• Moving furniture

• Increased pedestrian traffic

Parallel Arm Configuration

In a parallel-arm installation, the closer is typically mounted on the push side of the door, with the arm positioned approximately parallel to the door when closed.

This configuration is commonly selected because it provides:

• Reduced arm projection

• Cleaner push-side appearance

• Better protection from pedestrian traffic

• Compatibility with many exterior commercial doors

• Improved mounting flexibility

The Parallel Arm Bracket provides the frame-side connection needed to use the compatible FHO arm in this configuration.

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 would interfere with the door's required self-closing function.

Rated openings requiring hold-open capability generally require an appropriately listed automatic-release system.
