Matt,

Please read the warning on the McMaster-Carr website for this device:

Quote:
Warning! "Max. Pull, lbs." ratings are based on ideal conditions. Variations in iron content, thickness, and finish will reduce ratings. In lifting applications, do not use magnets more than 1/4 of their rated capacity.
From am engineering standpoint, this device is only safe for 40 pounds.

Regards,

Mike
