Apparently Home Depot carries this cable in the US (with a green coating) but here in Canada, I had to buy it on Amazon and have it shipped up. The cable you want is: the Loos Galvanized Steel Wire Rope, Vinyl Coated, 7×7 Strand Core, Black, 1/16″ Bare OD, 3/32″ Coated OD, 25′ Length, 480 lbs Breaking Strength (http://www.amazon.com/dp/B0013HICUY/ref=biss_dp_t_asn)
It’s an exact match and 25ft will do both doors and then some…
The cable on my other door is starting to fray and I will be trying the JB Weld instead of the hassle of soldering. I’ll let the group know how it goes.
