Don't confuse the stuff at the hardware store with EHS it really is FAR 
lower in strength.
The typical 3/16" galvanized wire rope is probably well less than 1000# 
breaking or working strength.
Galvanized wire rope can be found with strengths that vary over a wide 
range, but I don't think you'll find any at the hardware store that 
comes close to EHS.
