VerroLoc System

Circular Flange Ring System

VerroLoc Circular Flange Ring System provides an economical and efficient method of joining circular ductwork, suitable for both straight-seamed and spiral ducting.

The system uses two flange profiles matched to the required duct diameter, with an optional integral sealant for an airtight connection when correctly fitted. Duct sections are quickly assembled on site using the VerroLoc closure ring, with precision manufacturing ensuring easy installation.

Compared with conventional flanges, VerroLoc helps reduce fabrication and installation time while allowing duct sections to be easily removed for cleaning and maintenance.
