FRNC cables like our CLS 225 FRNC are designed to avoid the release of toxic matter in case of fire because they don not contain any halogens. That is why the CLS 225 FRNC is so well-suited for permanent installations in public buildings. Due to its small size, this speaker cable is enormously space-saving. It’s also easy to lay out thanks to the convenient torsional stiffness. The inner conductor consists of 2 x 2.5mm2 high-purity, oxygen-free copper.
