Made to Last: Strong material that won't damage coaxial, data, electrical, or other wire and cables, avoiding signal and electrical problems caused by staples. Thoughtfully Designed: Each cable clip includes a preinstalled nail to make installation more streamlined, and is wide enough for two coaxial cables, and many other audio, video, and electrical wires, cables, and cords. Indoor and Outdoor Use: These UV-protected anchor clips with solid plated nails are designed to be strong, simple to install, and lasting. Self-Locking: Added ridges lock the cable in place, allowing for automatic adjustments of cables, cords, and wires of many sizes, creating a near 360-degree grip, ensuring cables will not slide back and forth. Solid Construction: Each clip is precision machined from corrosion-protected materials to provide a secure connection.
