APPLICATION 2. On Top Of Roof Curb (figure 3).

Before installing, place the cone on top of the curb and mark the outline of the curb on the bottom of the

cone plate. Use snips to notch out the corners of the plate to match the curb. Bend down the extra

material with duckbill pliers to create a cap which fits over the curb. Attach the cone to the curb using

the same methods as described in Application 1.
