I used this to attach a 2 x 10 double head to a floor joist in an old house where the original 2 x 10 unplaned joists sagged a bit about 1/2 inch below the floor joist. I raised the top with the bottom of the joist and used the recommended structural screws to tie everything together securely. Even though it was indoors in the basement it was nice to have a Z coat on this mount. Very safe and well made, I always use Simpson, he's the best!
