I would have given it five stars, but the sliding handle is just a nut and bolt. So of course the nuts backed off and the handle fell off. Easily fixable, but a propper handle would have been better.
Used 2 of these beam clamps to lift a Precision Mathews TL-1440 lathe off of its shipping pallet. It weighs approximately 3600 lbs.
Worked flawlessly. Very good units for the use I had.
