- The spigot design incorporates a slight taper allowing the unit to be trimmed to an exact fit for any existing pipe or installation.
- A BFM® collar has a 52 mm (2 in) tail that can be cut back to suit existing pipework.
- BFM® Collars or BFM® Spigots for Tool Release installations require a 6 mm (15/64") hole in the top rim of the spigot. Pre-drilled TR spigots are available for purchase with your BFM® TR Connectors.
- Jacob flanges are available that allow the BFM® collars to be installed or removed in seconds without tools. We can provide 150# flanges for more heavy duty applications, or ferrule ends for sanitary applications.
