I don't have my measurements of this right now, but I can post tomorrow if needed. This serves a kitchen vent fan in my house. I want to take it off the side of the house to rehab it. Can can anyone tell me how it is likely to be fastened on?
It sits on a wood stand-off of some sort that probably sits on the wood siding that is under the cement siding shown. I backed off the 4 screws and gave it some gentle prying and tugging. It did not budge and don't really want to break it. I have too many other projects to attend to right now. IIRC, the square section that mounts to the house is 14" wide and tall and the duct is 10" diameter.
Should it pull off after removing the 4 visible screws or is it hooked to the duct somehow? If I need to replace it, is an exact replacement likely available?
