GS 100 A and GS 100 B ready for counter flashing

This process is over 10 years old and has had excellent results. We can say this is a time tested and proven method of flashing recessed windows that works great. The beauty is its simplicity. The process simply combines the use of pre-manufactured outside and inside corners. Outside Corners are called “A” pieces”. The inside corners are called “B” pieces.

The outside corners come in different return (or recessed depth) dimensions. They easily accept a sloped condition.

Available sizes for the “A” pieces are: 2 inch, 3.5 inch, 6 inch, 8 inch and 12 inch

The inside corners are all the same size. They also easily accept a sloped condition.

No rights and lefts are necessary, the corners work on both sides; and they work on the top of the opening as well.

All Corner Flash products are Proudly Made In The USA !  No imports here!
