Outdoor Vent-Hood on brick wall

[Bama_Electrical]

I have installed several of these on back porches on new construction and typically the builder will have a piece of treated 2X12 framed out to the edge of the brick to mount the vent-hood. I have a customer that just ordered a blaze 42” outdoor vent-hood and it has to be installed directly on the brick. Had thought about using tapcons but thought the vibrations of the vent-hood may eventually cause them to work their way out. Ideas? What do y’all typically use?

Caulk-ins would be my choice. How heavy is the hood?

What are Caulk-ins, never heard that term?

 

[scrubbin]

I believe they can be called calk-in or caulk-in. same to me

Caulk-In Anchors​

Also known as machine screw anchors or expansion caulk-in anchors, these anchors can be used in concrete, brick, and stone. They consist of a pre-assembled internal machine screw, as well as an expander cone and lead-alloy caulking sleeve.

I don’t have the hood in hand yet, but with the fan, thinking about 130lbs.

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

We used to call the lead anchors.
Maybe they' don't use lead anymore.

That's what we call them, never heard caulk-in before.

We used to call the lead anchors.

What we called lead anchors were the expansion shields that you put in the hole and use a lag bolt with. There are also the smaller ones for wood or sheet metal screws. Those had a fiber outer covering with a lead center. Those have been replaced by plastic anchors.

One brand of those was Rawl, but never seen them used on wood or sheet metal. They were most often used in plaster or masonry around here.

I've seen that style as well.
This is what I'm talking about.

A lag shield is what we called it.

He said "wood or sheet metal screws."

1/4" tapcons will work fine, each tapcon is rated at 250lbs per fastener in CMU, brick will give a higher rating. The biggest thing with tapcons is not over driving when installing and not reusing the fastener.

And don’t use an impact driver.

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.

 

[kwired]

And don’t use an impact driver.

Does that include the impact action you get if driving with a hammer drill and tapcon drill/driving tool? Not entirely the same impact action as a true impact driver but still some similarity compared to just straight constant torque action.

I don't always read all of the works

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