Southwark Metal 84ST_1-1/2X8 Ductboard Collar Tap 8 Inch

Product Description

The SOUTHWARK METAL 84ST_1-1/2X8 is an 8-inch ductboard collar tap fabricated from hot dip galvanized steel with a 1-1/2-inch tab. This fitting connects round duct to ductboard panels, creating a secure branch takeoff in low-pressure air distribution systems. The galvanized construction resists corrosion in both conditioned and unconditioned spaces. HVAC sheet metal technicians and duct installers use this collar tap when transitioning from rigid fiberglass ductboard to round branch lines in residential and light commercial supply systems. It meets ACCA and SMACNA applicable standards for duct construction quality.

This collar tap is suited for installation in residential and light commercial HVAC duct systems where ductboard panels serve as the primary air distribution medium. The 8-inch diameter fits standard round branch duct of the same size, and the 1-1/2-inch tab provides a positive mechanical connection to the ductboard surface. Typical applications include supply branch takeoffs in attic, crawlspace, and indoor air handler installations where ductboard is the chosen duct material.

Key Features

• 8-inch diameter fits standard round branch duct for direct branch connections
• 1-1/2-inch tab provides a secure mechanical attachment to ductboard panels
• Hot dip galvanized steel construction for corrosion resistance in HVAC environments
• Meets ACCA and SMACNA applicable duct construction standards
• Designed for low-pressure supply air distribution systems using ductboard

Compatibility

Designed as an OEM-style ductboard collar tap for use with standard fiberglass ductboard panels in residential and light commercial HVAC duct systems requiring an 8-inch round branch connection.

Installation Notes

Installation should be performed by a qualified HVAC technician or sheet metal installer following SMACNA and ACCA ductwork guidelines. Shut down the air handling equipment and confirm the system is de-energized before cutting into ductboard or modifying any duct section. Use appropriate sheet metal tools and duct sealant or approved tape at all connections to maintain system air tightness per local mechanical code requirements. Handle cut edges carefully to avoid injury from sharp galvanized steel.
