Installation

Greenheck Dampers may be supplied with factory hemmed 20 ga. (1mm) sleeve for use with drive slip and s-slip joints. Sleeves and duct may be field hemmed by folding back the vertical sides a maximum of 1/2 in. (13mm) (as shown in Figure 1) to accommodate the 1 in. (25mm) wide drive slip.

Join damper sleeve to duct at top and bottom sides using any s-slip (See Figure 2).

Drive slip connection is used to connect the vertical sides				Duct	Drive slip
of the damper sleeve to the duct. Cut a length of drive slip
connection a maximum of 4 in. (102mm) longer than the
vertical duct dimension. Guide the drive slip connection				Figure 1
onto the side members securing it over the hemmed edges
until the connection extends beyond the top and bottom
sides of the damper sleeve/ duct. The extra length should
be hammered flat overlapping all four corners.
