The TimberTech CableRail is meant for use with composite rail systems that have structural wood posts inside composite sleeves. Quick Connect fittings fasten the cable to the posts: Simply drill through the sleeve, screw the fitting into the wood post, then connect the cable to the fitting’s swivel and tighten it with a wrench. Cost is around $355 for a 6-foot section, including the composite railing, cable, and connectors. If you lose a connector, you can buy one for $24.
