Sizes offered. Seven sizes of cable are offered for the CAI Cable Railing System: 1/8”, 5/32”, 3/16”, 1/4”, 5/16”, 3/8”, and 1/2”.
Cable construction. For most applications, we recommend 1x19 construction, type 316 stainless steel cable. 1x19 construction cable is engineered to hold static loads without stretching, and it is relatively stiff. Other cable constructions can be used, such as 7x7 or 7x19, but they are rarely recommended because of their elevated levels of stretch and lower breaking strengths in comparison to 1x19 construction (see chart).
Cable coating. Cable can be special ordered with a PVC coating in any standard (PMS) color. If PVC coated cable is to be used with metal framed railings, special caution should be used because hole specifications for frame components can change and, in some cases, special hardware may be required. If you are interested in using coated cable, please contact the factory for any necessary special hardware or design specifications.
