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).
