WOF80 - 6-9/16” window and door corner sill pan flashing with back-rib and removeable 1/2” back-dam
The black 6-9/16” corners and straights will have several new features. First we have added an additional one inch over-lap on each ends of our corners and on one end of our straights. This will enable you to over-lap the joints before you cover the joint with butyl tape.
Second we have lengthened the black straights to 32 inches. This allows you to use just two straights and the two corners to do a 72” door or window unit.
The third innovation is that we took the back rib of our original corners and straights and jointed it with a half inch back-dam. We made it so the back-dam can be easily removed leaving the back rib so this now lets you use the 6 9/16” blacks to do any type of door, double hung and vinyl window.
So if your area of the country is not requiring the half inch back-dam you can remove it and picture frame your windows, or a direct return method. You just leave the back-dam on with your doors and with windows where you are using the traditional stool and apron method of trimming them out.
One case of our non-handed sill pan corners (50 per case) combined with one case of our 32-inch straight sill pans (25 per case) will completely protect 25 standard 3' 0" widow or door openings. If your openings are larger, simply purchase additional straight sill pan pieces and cut to fit.
