ADAPTERS
TAPERED INCREASER (TIN Ø)
The Tapered Increaser Adapter is used for a diameter change in the vent
system. Used when there is a sufficient length for duct run available for the
size change. The TINØ is uses 2" of length per 1" increment diameter change.
The TINØ is considered to have the same load strength as a straight duct. See
Figure 29.
