The Feeney I've installed uses a decent grade of stainless and hasn't needed any tensioning in 3 years.This links directly to SS rod railing. SS rods don’t require constant tensioning cables do. One caveat; kids like to climb up horizontal anything, some fall with all the risk that involves. Also, bent rods may be unsalvageable, which can be expensive down the road. So, great for those with no kids, drunks or jackasses to be concerned about.
