nVent CADDY Cat HP J-Hooks are the heart of the nVent CADDY Cat HP System. The J-Hooks have a wide base design and smooth beveled edges to provide a large bending radius for current and future high-performance data cables and fibre optics. Individual nVent CADDY Cat HP J-Hooks can be fastened directly to the building structure or can be used to expand existing nVent CADDY Cat HP J-Hook cable supports.
