I have to second that. I have never seen a Sullivans chute like that. If it is truly a Sullivan's chute, they have come a long way. The back frame looks like it is held up by a single piece of flat aluminum? Ours have more of a channel type deal the frame folds up to. Also the bar holder at the top looks like it is hanging a tick, has it been broken and re welded, or is it just bent? either way, it is a good price for an aluminum chute.
