6" X 18" Pics attached. Bracket is aluminum and can be polished. Clamps are stainless. Top 2 fittings are intakes 1-1/4 Bottom fittings are out to sea pumps etc. 2 are 1-1/4 and 2 are 3/4 which I used for relief valve and flush. I have some fittings and two 1-1/4 stainless ball valves available.

I have 2 exactly the same sea strainers as fireboat availlable and internals for a 3th one but no brackets whit them ,bought them but way to big for me
