The BSC PREFERRED CTUV21120 is a pack of 100 black, UV-stabilized nylon cable ties designed for permanent fastening of cords, cables, bags, and bundled materials in outdoor or high-UV environments. The black colorant is integrated throughout the nylon for UV resistance, not a surface coating, making these ties suitable for continuous outdoor exposure without degrading or becoming brittle over time. The locking mechanism is tamper-proof, meaning once fastened, the tie cannot be released without cutting. These are sold as a case of 100 units and are commonly used by electricians, contractors, and facilities technicians who need a reliable, weather-resistant bundling solution.
These cable ties are well-suited for outdoor electrical conduit bundling, utility installations, irrigation systems, fencing, signage mounting, and any application where prolonged sun or weather exposure would degrade standard natural-nylon ties. The UV stabilization makes them a direct choice over standard white or natural nylon ties when the install location sees direct sunlight or extreme temperature cycling. They are also used in packaging and shipping operations for securing bags and covers.
Designed as a general-purpose outdoor cable tie for use in electrical, mechanical, packaging, and facilities applications where UV resistance is required. Equivalent to part number S-14040.
Cable ties of this type are installed by hand or with a cable tie tensioning tool for consistent pull force and flush cutting. When used in electrical applications, follow applicable NEC guidelines for cable bundling and securing. Do not overtighten around insulated conductors to the point of deforming the insulation jacket. Cut flush after cinching to avoid sharp edges that can cause injury during future service.
