Air Flow Products MTD114 Conical Spin-in Takeoff Damper 14 in

Product Description

The AIR FLOW PRODUCTS MTD114 is a 14-inch metal duct conical spin-in takeoff fitting with an integrated damper, designed for use in sheet metal ductwork distribution systems. The conical spin-in design locks into round openings in main trunk ducts, creating a secure, low-leakage branch connection. The built-in damper allows airflow balancing at the takeoff point without requiring a separate balancing damper downstream. This fitting is typically installed by HVAC sheet metal mechanics and service technicians during new construction or duct retrofit work.

The MTD114 is suited for residential and light commercial forced-air HVAC systems where branch runs are tapped off a main rectangular or round sheet metal trunk. The conical collar seats firmly into a field-cut or factory-punched hole in the trunk duct, and the integrated damper provides on-the-spot volume control. This type of fitting is a standard component in supply-side duct distribution layouts.

Key Features

• 14-inch conical spin-in collar for secure, low-leakage trunk connection
• Integrated damper for airflow balancing at the branch takeoff point
• Metal construction for durability in forced-air duct systems
• Spin-in design installs without separate fasteners at the collar seat
• Eliminates the need for a separate downstream balancing damper

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 14-inch branch connections in residential and light commercial sheet metal forced-air duct systems.

Installation Notes

Installation is performed by licensed HVAC technicians or qualified sheet metal mechanics. Power down the air handler or furnace and close the disconnect before working inside the duct system. The conical collar is inserted into a correctly sized hole in the trunk duct and rotated to lock in place before securing the damper and connecting the branch duct. Follow local mechanical codes and SMACNA duct construction standards for proper fitting selection and sealing requirements.
