Southwark Metal ATTRP_8IN Duct Saddle Takeoff 8 Inch

Product Description

The SOUTHWARK METAL ATTRP_8IN is an 8-inch round sheet metal duct saddle takeoff fabricated from hot-dip galvanized steel. It is designed to create a branch connection off a main rectangular or round duct trunk, directing conditioned air into a branch run. The Air-Tite construction reduces air leakage at the takeoff point, which matters on systems where duct tightness is a design target. HVAC installers and sheet metal contractors specify this fitting for residential and light commercial forced-air distribution work where a clean, secure saddle-style branch tap is required.

This saddle takeoff is used in forced-air duct systems where a round branch duct needs to be tapped off a main duct trunk. The round, saddle-style design seats against the duct surface and is secured to create a branch opening. It is commonly installed during new construction rough-in or during duct system retrofits and additions. The 8-inch diameter suits branch runs serving larger zones or longer duct runs where adequate airflow velocity must be maintained.

Key Features

• Hot-dip galvanized steel construction resists corrosion in attic, crawlspace, and mechanical room environments
• Air-Tite design minimizes air leakage at the branch connection point
• Saddle-style fitting seats against the main duct for a stable, secure branch tap
• 8-inch round outlet matches standard round duct and flex duct sizing
• Meets ACCA and SMACNA applicable standards for duct fitting construction

Compatibility

Designed as an OEM-style sheet metal duct fitting compatible with standard forced-air duct systems using 8-inch round branch connections per ACCA and SMACNA guidelines.

Installation Notes

Installation is typically performed by licensed HVAC technicians or sheet metal contractors following SMACNA duct construction standards. The main duct trunk must be de-energized and the air handler shut down before cutting the branch opening. Secure the saddle fitting to the main duct with sheet metal screws and seal all joints with UL 181-listed mastic or foil tape per local mechanical code requirements. Do not install without proper sealing, as unsealed saddle connections are a common source of duct leakage.
