This battery cable is 4' end to end give or take an inch.  It is flexible with about a 2-2.5 inch turning radius.  One side is for a 1/2" bolt at .530" and one is for 3/8" at .400".  This will be shipped without the box if you choose the flat rate envelope for shipping.  If you have any questions feel free to ask.  I only ship to the US.
