use pliers or vice grips to squeeze together the Tabs so they will accept the slots in the Locking

accommodate offsets and direction changes, refer to rotating clamp installation instructions.
5. Center the Coupler Band around the completed joint and tighten the 7/16" nuts with a hollow nut
driver or deep socket. If the assembly must be weather tight, apply a 1/4" bead of sealant to the
inside top edge of the Coupler Band approximately 1 inch down from the edge.
4. Position the Locking Strap slots over the Tabs, making sure each slot encompasses both Tabs.
Tighten the Locking Strap with a 7/16" hollow nut driver or deep socket, take caution not to over
tighten the clamp causing the vent to collapse.
