Greenheck drive slip connections (S & Drive) are used on
the side of the hemmed sleeves and the S-slip joints are
used on the top and bottom. Standard drive slips are UL
tested breakaway connections on dampers 20 in. (508mm)
high and less.
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
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
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.
