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. “UL CLASSIFIED (see complete marking on product)” “UL CLASSIFIED to Canadian safety standards (see complete marking on product)” Standards UL 555 & 555S Classifications Filed at UL under Listing #R13317 r® us Sleeve S-slip i Drive Slip i f Duct Sleeve Top and Bottom Duct to Sleeve Connection Vertical Sides Duct to sleeve connection Figure 2 Figure 3 [^GREENHECK Copyright © 2007 Greenheck Fan Corporation #468769 Drive Slip Breakaway Connection Rev. 2 December 2007 P.O.
