PRESSED STEEL DEMIST VENT
Here's a strong steel vent with a black, textured, matt black, powder coat finish.
It has a 40mm O.D inlet and a 200mm wide x 5mm, letter-box style outlet.
There are two little hook brackets welded near the outlet.
A simple mounting option would be two small pieces of aluminium angle (not included),
riveted near the outlet.
