Hardware for suspending wood beams from a wall
I made a cedar hand rail and came up with a stand off to set it off of the posts by a couple of inches.
I used a carriage bolt but you could do it with a lag bolt or machine bolt.
Lag into house, washer, sleeve, washer, lumber with recessed/counter sink hole, washer, lag head.
