Seal-tite 1729-10 Spin-in Duct Collar 10 in Tab Mount Scoop Damper

Product Description

The SEAL-TITE 1729-10 is a round spin-in duct collar designed for duct board applications where a 10-inch branch connection to round pipe or flexible duct is required. The collar inserts into a field-cut opening in the duct board and locks in place using mounting tabs, creating a stable, secure fit without additional fasteners. An integrated scoop directs airflow into the branch run, improving distribution efficiency. A built-in damper allows the technician to regulate airflow volume at the takeoff point. HVAC installers and sheet metal mechanics use this collar as a standard component in residential and light commercial duct systems.

This collar is suited for duct board trunk systems where branch takeoffs feed supply registers through round pipe or flex duct. The tab-mount design is compatible with standard duct board construction methods, allowing a clean, flush installation. The integral damper makes this collar appropriate for applications where zone balancing or individual register control is needed at the takeoff rather than at the register boot.

Key Features

• 10-inch round opening for connection to round rigid pipe or flexible duct
• Tab-mount design secures collar in duct board without screws or sheet metal fasteners
• Integrated scoop promotes smooth airflow entry into the branch duct
• Built-in damper allows airflow adjustment at the takeoff point
• Spin-in installation for fast field fitting during duct system assembly

Compatibility

Designed as an OEM-style replacement and new-installation component for duct board trunk systems requiring a 10-inch spin-in branch collar with damper control.

Installation Notes

Installation is performed by licensed HVAC technicians or qualified sheet metal mechanics. Power down the air handling unit and confirm the system is de-energized before cutting into any duct board section. Cut the duct board opening to the correct round diameter using a hole saw or duct board knife, insert the collar, and fold the mounting tabs to secure. Adjust the integral damper only after the system is running and airflow balancing is performed.
