Yep. It looks like this:Good question. Are you saying you want to go directly in the brick??
The top outer holes on the mounting bracket are only 4" apart, spaced 9" to the bottom. it comes with 5/16" x 2.5" lag bolts for wood. I'm thinking if I get large sleeve anchors 5/16 or bigger, and at least 3", it should work okay if I put the top ones in the mortar line. But even at that, 45 lbs. would be a lot of stress on a small area.
I've googled like crazy, but it's amazing how little info there is on brick anchors- it's all on concrete or cinder block, it seems. But I did find the super expensive chemical anchors interesting.
And I've thought of using multiple tapcons to scab a thick block of wood up there, spreading the stress, then using the bolts that came with it, but that woudn't be a very pretty installation.
I've reached out to the seller, but QC Supply sells farm & livestock equipment, so I doubt they can tell me anything about it. Highly rated heavy duty fan, but Chinese made of course.
