After seeing this: http://www.hvac-talk.com/vbb/showthr...threadid=74651
and seeing similar things at my own condo building, how do people tie down condensers so that they won't go flying? At my own building, metal straps were used, but at least half the straps failed, tearing somewhere around the middle of the strap on most, with just a few tearing at the screws. While my straps held, I still went back in there and tap-con'd the base to the wooden mounting rails on the roof, but still not sure that's enough. Any suggestions?
