Swing N Slide Cast Steel Extra-Duty Swing Hanger (2-Pack) - 1 Each

Is this for a "pair" of hangers or just one. Your description does not say.

Does this set of swing hardware include the proper size bolts for attachment?

Do these hangers include spring clips or s hooks to attach the swing chain?

We had a frame welded from steel pipe. Are these hangers suitable to used with steel pipe swing frames?
