Application and Design
Ductmate
®
is used to connect a damper sleeve to
a rectangular duct when a tight duct connection is
required. The Ductmate connector gives a nearly
airtight cross connection without the use of slip joints,
and is an acceptable breakaway connection when
installed properly.
Particular attention should be given to the length of
the sleeve extending beyond the wall or floor. The
determining factor is dependent on whether or not
there is an actuator and/or access door. If there is
no actuator and/or factory mounted access door, the
maximum is 6 inches (152mm) extending beyond the
wall or floor. If there is an actuator or factory access
door on the side of the wall, the maximum is 16 inches
(406mm).
Versa-cleats are available in packages of 10, 25, or
50. See installation instructions for spacing of cleats
(468502 Quick Connect Breakaway Supplement).
