Installation Manual
FC Series
Fast Clamps
Warning
Sheet metal will have sharp edges. Always
protect your hands during installation.
The tabs are sized for the weight of the fan.
The duct should be supported by other
means. Always consult local code when
installing our products. If special supports
are required in anticipation of earth quakes,
the FC clamps are not intended to meet
these requirements.
General Information
The FC Clamps are intended to simplify fan
installation and isolate fan vibration from
rigid metal duct. FC Clamps are convenient
in installations where regular removal of the
fan is necessary for inspection and cleaning.
FC Clamps are available in sizes 4” through
20” to fit corresponding duct sizes.
FC Clamps in sizes 4” through 12” are
equipped with integral hanging tabs. When
used with model FR or FG fans, these tabs
can be used to suspend the fans. If used for
that purpose, two FC clamps are required.
DO NOT hang FKD Series fans from these
tabs. FKD fans are equipped with integral
brackets for suspended installation.
