If you rent out sound, lighting or audio/video equipment, this might be the Cord-Lox 412R Cord-Lox solution for you. The Rivet Series is designed to stay on the cord permanently, so customers are more likely to return your cables coiled up and ready for your next job. This also makes your cords easily identifiable and with our different colors and sizes, they are even organized for categorization. Custom colors, sizes and logo printing are available.
