The high performance j-hooks are built with steel j-hooks over-molded with polypropylene for an easy cable slide. The “snap-lock” retainer is easy to use and re-use, firmly securing cables every time and eliminating the use of cable and Velcro ties. Each J-hook has a 2” wide base support, to prevent cable kinks. They're callus listed, plenum rated, RoHS compliant, and are available in 1”, 2”, 3”, and 4” sizes, along with a variety of hardware accessories for all of your cable management needs.
