Very sturdy hangars!  (The package came with four individual hangars, or two sets of pairs of two, which was twice the amount promised.)  We used two of them them to hang up a two-person porch swing, which required the additional purchase of four 2-1/2" lag screws to attach the hangar to the wooden joists in the porch ceiling cover.  Planning to use the two extra hangars at other locations for future items such as climbing ropes/ladders for the grandchildren.
