       I'm not a fan either. My statement was based on the fact that if one is
rated at 2500 lbs., then two must be rated somewhere around 5000 lbs. Since
3'16" EHS has a breaking strength of 4000 lbs., that might be in the range of
the capability of two properly installed screw-in anchors. 

     Or not.
