Reference#: 67684


CADDY CAT21HP24SM 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, fiber optic cables, innerduct and coax cables. Individual CADDY CAT21HP24SM J-Hooks can be fastened directly to the building structure or can be used to expand existing CADDY CAT HP J-Hook cable supports. The J-Hooks are designed to provide a strong and stable pathway support installation. The attached hammer on flange (24SM) is pre-installed, making installation fast and easy on 1/8" Thru 1/4" flanges.
