Outdoor Vent-Hood on brick wall

[Knuckle Dragger]

Maybe you could use "loctite" on the machine screws and add a few dabs of and epoxy or silicon between the unit and the substrate at a few choice locations to help hold it up.

The OP expressed concern if there is constant vibration. Also, holding power is very dependent on the integrity of the masonry work.

those figures were based on cmu, which is weaker than brick. There are figures for poured concrete which are much higher. I couldn't even find data about the anchors originally posted.

Are these not much different than many inside vent hoods as far as weight, size, etc.?

If so I wouldn't have too much concern over supporting them from brick, even plastic cone anchors likely would hold up fairly well as most these aren't that heavy. Downward load probably is less concerning than any potential pull out loading, so the further they protrude from the wall the more potential leverage there is for pull out pressure on whatever fastening means is used.

A pic of the hood or a similar one might help us help you.

Here’s the specs, don’t know if that’s actual weight or shipped weight.

OP posted the specs, not a light unit.

If the brick is only a veneer you might want to consider going through the brick into the substrate.

I've had good luck running them in with an impact, you can't go wide open. I hold just enough trigger to turn the fastener slowly and you see right when its tightened up.

For me, using an impact seemed to always pulverize the “threads” being cut into the concrete. Maybe I was doing it wrong. I now always use a Bosch non-impact driver and never have a problem.

I used a hammer drill with the included bit to create the hole for the Tapcon, but always just used the "screw" setting on my DeWalt to drive the screws.

Same.

Can't go wrong with drive pins, either. Used a lot of red head anchors for heavy stuff, too. If it seems sketchy, add one or two for peace of mind.

I just got to thinking what is the point of an outdoor vent hood? Do you run the vent to an interior location?
