Weght limit for SolidSteel shelf/cones?


I own a SolidSteel rack (5 series) and am considering buying a turntable that weighs just under 50 lbs. Is this too much for the 3 cone points that hold up the top shelf of the SolidSteel? The cones seem to be aluminum--not the hardest metal.

Thanks for any advice.

Nothing to worry about. Those shelves and cones are solid!
I've never had a problem with any amount of weights and those little points are just as sharp as ever!
