Secure Flex comes with an adaptor (catalog no. 87L00) that can be fitted
to the appliance collar or the inclined channel end of the last Secure Vent
section (SV4.5) in a rigid system. Align the dimpled end of the adaptor
over the previously installed section or appliance collar, adjusting the
radial alignment until the four locking dimples of the adaptor are aligned

collar. Push on the adaptor until it fully engages, then twist the adaptor
clockwise running the dimples down and along the incline channels until
they seat at the end of the channels. See Figure 1.
