Deluxe Aluminum Cord Grips are UL Listed and CSA Certified for use in both indoor and outdoor applications to prevent cable pullout, to control arc of bend, and to provide a tight seal against environmental elements such as dirt, moisture and coolants. Cord grips are available in a wide range of conduit sizes from 1/4" to 3" in straight, 90º and 45º styles. A uniquely designed combination tightening surface with both a hex area and a knurled surface provides extra gripping for initial hand tightening.
