It has a unique design with a combination tightening surface that includes both a hex area and a knurled surface. The grip features an anti-friction washer that fits between the nut and bushing for easier compression. It is UL Listed and CSA Certified for use in both outdoor applications to prevent cable pullout, control arc of bend, and to provide a tight seal against environmental elements such as dirt, moisture, and coolants.
