Honeywell 26025f/u Damper Arm 3/8 Inch Shaft

Product Description

The HONEYWELL 26025f/u is a damper arm designed for use with motorized damper assemblies in HVAC zoning and ventilation systems. This component connects the damper actuator to the damper blade, transmitting rotational force to open and close the damper as the control system commands. It is engineered to fit a 3/8-inch shaft, providing a direct mechanical interface between the drive mechanism and the damper. Licensed HVAC technicians and sheet metal mechanics install this part during new zoning installations and as a replacement in existing systems where wear or damage has compromised damper operation.

This damper arm is suited for residential and light commercial HVAC zoning applications where motorized round or rectangular dampers are used to regulate airflow through individual zones. It is a typical service replacement for actuator-driven damper assemblies and is appropriate for installations requiring precise, repeatable damper blade positioning controlled by a zone panel or thermostat system.

Key Features

• Fits 3/8-inch damper shaft for secure mechanical coupling
• Designed for motorized HVAC damper assemblies in zoning systems
• OEM-style replacement for restoring damper actuator-to-blade linkage
• Supports reliable airflow control in single- and multi-zone applications

Compatibility

Designed as an OEM-style replacement damper arm for motorized HVAC zoning damper assemblies using a 3/8-inch shaft interface.

Installation Notes

Installation should be performed by a qualified HVAC technician. Shut down the air handler and de-energize the zone control panel and actuator before removing or installing the damper arm. Confirm the shaft diameter measures 3/8 inch before fitting the arm, and verify the arm seats fully and is secured against slippage before restoring power. Follow applicable mechanical and HVAC codes during service.
