Seal-tite 1203-3010 Transition Take Off 30x10 in

Product Description

The SEAL-TITE 1203-3010 is a transition take off fitting designed for HVAC duct distribution systems. It connects a main trunk duct to a branch run, redirecting conditioned airflow from the supply plenum or trunk line into a lateral duct. This type of fitting is a standard component in sheet metal duct fabrication and is installed by HVAC technicians during new construction or system retrofit work. The 1203-3010 measures 30 inches by 10 inches, making it suited for medium-to-large capacity residential or light commercial duct systems where a properly sized branch connection is critical to maintaining system static pressure and airflow balance.

Transition take offs like the 1203-3010 are used in forced-air heating and cooling systems where trunk-and-branch duct layouts are employed. The fitting transitions between the main duct trunk and a smaller branch duct run, allowing installers to tap off airflow at a designated point along the duct system. This fitting is appropriate for residential applications and light commercial builds where sheet metal ductwork is the specified distribution method.

Key Features

• 30-inch by 10-inch throat dimensions for medium-to-large branch connections
• Designed for trunk-to-branch duct transitions in forced-air HVAC systems
• Compatible with standard sheet metal duct fabrication and installation methods
• Supports proper airflow distribution and static pressure balance across branch runs

Compatibility

Designed as an OEM-style sheet metal fitting for use in residential and light commercial forced-air duct systems utilizing trunk-and-branch supply configurations.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with sheet metal ductwork and local mechanical codes. Shut down the air handling unit and confirm the system is de-energized before cutting into any existing duct trunk. Secure the fitting to the trunk with sheet metal screws and seal all joints with listed duct sealant or UL-listed tape per applicable mechanical code requirements. Support the branch duct run independently to prevent stress on the take off connection.
