[QUOTE="mackerr, post: 121822, member: 307"] Re: ATM Flyware double stud fittings - Load ratings and angles? I expect they have arbitrarily derated the hardware for some reason. According to that Allen Products link the only stud fittings permitted for overhead use have a 500lb vertical WLL and a 400lb 90º WLL. The track itself is rated at 900lb vertical and 300lb at 45º with those double stud fittings. Of course it is [i]possible[/i] to use fittings not rated for overhead use, and they derate to 160lb at 90º, but the track derates to 150lb at 45º with those single stud fittings. Mac [/QUOTE]
