The jumpover bracket can be used on dampers 10 inches or higher (under 10 inches the blades are too small to
support the bracket).

1. To determine which blade to attach the jumpover bracket to the damper blade, always attach to the same drive
blade that contains the actuator or manual quadrant.

2. Drill the jumpover bracket into the drive blade. Attach jumpover bracket to the blade with TEK screws.

3. A support bracket will need to attached to the drive blade. The support bracket will arrive with the holes
pre-drilled. This bracket will need to be cut to length depending on the size of the damper. Drill support bracket
into the blade as shown (You may use duct tape, clamp, etc. to keep bracket in place while drilling).
