Snappy 89-12 Round Ductboard Starting Collar 12 Inches

Product Description

The SNAPPY 89-12 is a 12-inch galvanized round ductboard tab collar starting takeoff designed for use in low-pressure sheet metal and ductboard duct systems. This fitting connects round flex or rigid duct branches to ductboard trunk lines, providing a secure, airtight starting point for supply air distribution. The tab collar design locks into the ductboard face without additional fasteners, simplifying installation and reducing labor time. At 0.80 pounds, it is lightweight enough for overhead work and one-person installation. Sheet metal fabricators and HVAC installers use this type of fitting on residential and light commercial ductboard systems where clean, reliable branch takeoffs are required.

This starting collar is suited for residential and light commercial HVAC installations where ductboard is used as the primary trunk material. It provides the connection point for 12-inch round branch runs supplying individual zones or rooms. Typical installations include horizontal air handler setups and attic duct systems built with rigid fiberglass ductboard. The galvanized steel construction resists corrosion in the moderate-humidity environments common to conditioned attic and crawl space installations.

Key Features

• 12-inch fitting size for standard round duct branch connections
• Tab collar design seats directly into ductboard face without separate fasteners
• Galvanized steel construction for corrosion resistance
• Lightweight at 0.80 pounds, suitable for overhead and single-technician installation
• Starting takeoff configuration establishes the branch run at the trunk face

Compatibility

Designed as an OEM-style replacement and standard fitting for residential and light commercial ductboard trunk systems requiring 12-inch round branch starting takeoffs.

Installation Notes

Installation is typically performed by licensed HVAC technicians or sheet metal fabricators. Power down the air handling unit and verify the system is depressurized before cutting into an existing ductboard trunk. Score and cut the ductboard face to the correct diameter, seat the tab collar firmly, and seal all edges with UL 181B-rated tape or mastic per local mechanical code requirements. Do not rely on the tab collar alone as the sole air seal.
