It becomes a new roof support bracket.
If it was a normal one, it could not be supported without adding reinforcement to the nojiku board.
In addition, it was very difficult to support the roof bracket when a large hole was made in the roof.
If you use this, you can easily install it by drilling a hole in the roof board and covering it from above without any work such as reinforcement.
Or it will be installed from the ceiling behind the attic to the rafters.
The plate is made of SUS304 with a thickness of 2 mm, so unlike conventional products, it is possible to firmly support the chimney without falling down from the hole on the roof of the sheathing board.
We have confirmed that it can be used up to a 9 inch slope.
In order to use a rectangular slope (10-inch slope of 45 degrees), it was necessary to widen the elliptical hole in the plate.
Please refer to the photo with the curing tape applied.
