I used these brackets to hang a large metal swing in my backyard.  The brackets were well made and the paint coatings were good.  The included fasteners were appropriate for wood timbers and the weight of my swing.  My only issue was that the inside dimensions of the leg pieces were slightly smaller than the treated 4X4 timbers I purchased at the local building supply store, and I had to shave enough wood from the legs to allow them to fit into the pieces.
