Integral nylon spring eases the cable into a lazy bend; prevents kinking and assures longest cable and product life. Easy installation—unique fingers securely snap into a range of panel thicknesses - up to .125" (3,2 mm) - with no tools or locknuts required. Sealing flange prevents sealing washer displacement due to water velocity to ensure a liquid tight IP 65. Eliminate need for locknut or threaded hole to achieve liquid tight seal at panel; perfect for low clearance installation where locking nut access is limited. Ratchet design of sealing nut assembly provides superior anti-vibration and ensures a firm grip on the cable. Foam washer included. Rotation prevented when used in Double D mounting holes.
