This bracket is exactly what i needed for a long-beam swing set (16 foot beam) the one caution for this part is that it is intended to go in the centre of a long beam. The only draw back is we actually had to shave the end of the 4x6 to get it in.
Worked really well to hang my gymnastic rings. All stainless, even the lag bolts are stainless. This hanger is perfect as it will handle the weight, is stainless steel, and is easy to install.
After a ton of looking these seemed to be the choice. Very decent price and the quality is very strong. The hardware is of good quality.
