I LOVE replacing old Andersen Permashield DHs. I order my replacements only 3/8" smaller than the opening because of the smaller outside stops. 1/2 " thickness on the inside stops. If it's in brick its an easy L bend picture frame cap. 10 mins. Like Jake said.......GRAVY.

On a goood day we can set and cap and stop about 25 of these. BOO YA:thumbup:
