Pellet 45° ring
matt black painted
Ring is used as cover piece on the wall for the entrance hole of a chimney. The 90° is used when the piece to be inserted has an angle of 90° to the wall whereas the 45° when this angle is 45°. The 90° ring is also used when the flue crosses through a wall to continue in the next room: in this case two rings have to be installed, one for each side of the wall, for a pleasant finish.
The maxi one has a widest diameter to be able to cover a larger hole on the wall.
