The DURO DYNE 10283 is a Versalon-style duct connector designed for use with TDC (Transverse Duct Connector) and TDF (Transverse Drive Flange) duct joining systems. Fabricated from 24-gauge steel, this connector measures 4 inches by 4 inches and provides a secure, rigid joint between rectangular duct sections. It is installed by HVAC sheet metal mechanics and duct fabricators working on commercial and residential air distribution systems where flanged duct connections are specified.
This connector is suited for rectangular ductwork assemblies that use TDC or TDF flange joining methods, which are common on commercial HVAC projects and light industrial installations. The 4 x 4 inch profile fits duct sections of matching dimensions. Its steel construction is appropriate for low-pressure and medium-pressure supply and return air systems where sheet metal ductwork is required by design or code.
Designed as an OEM-style replacement and standard component for rectangular ductwork systems utilizing TDC or TDF transverse flanged connection methods.
Installation should be performed by a licensed sheet metal mechanic or qualified HVAC technician. Shut down the air handling system and de-energize associated equipment before beginning duct work. Connectors should be seated fully into the duct flange and secured per applicable SMACNA ductwork installation standards. Inspect mating duct flange dimensions before installation to confirm proper fit.
