Screw Hole Changes

We have made changes in the screw holes we provide with our vent shields. Depending upon pitch, we may only provide two holes in the front. The sides may have only one hole, and there may or may not be a hole in the back. We do this because the steeper the pitch, the more area is gripped by the shield to the roof, and as such more than two screw holes is redundent. Also the hole in the back is rendered useless by high pitch units as you cannot get a driver behind it.
