Key Features
78 LB Heavy-Duty Tensile Strength
Each tie withstands up to 78 LB of pull force — sufficient for heavy cable bundles, thick garden structures, HVAC ductwork, and industrial pipe runs. This professional-grade strength ensures your bundles stay exactly where you put them, even under sustained load or vibration.
Industrial-Grade Nylon 66 Construction
Nylon 66 is the gold standard for industrial fasteners — it resists abrasion, chemicals, and mechanical fatigue far better than standard nylon. These ties won’t stretch under tension, crack under UV exposure, or become brittle in cold conditions, ensuring long-term reliability in demanding environments.
UV & Heat Resistant — All-Weather Durability
Engineered to operate from -40°F to +185°F, these ties are built for continuous outdoor use in sun, rain, and extreme temperatures. The black pigment provides an additional UV barrier, making them ideal for outdoor cable management, garden structures, and exposed construction applications.
Extended 12-Inch Length (5.2 mm × 300 mm)
The 12-inch length handles bundles that shorter ties simply can’t reach around — thick conduit runs, multiple hose bundles, large garden trellises, and wide cable trays. The 5.2 mm width provides the surface area needed for a rock-solid grip under heavy loads.
Self-Locking One-Way Ratchet Mechanism
The precision-engineered self-locking head cinches down firmly with each pass and won’t release under tension. Tool-free installation means fast deployment on job sites, in workshops, and across any high-volume application.
Perfect for:
- Industrial conduit and cable tray management
- Automotive wiring harness and hose bundling
- Garden fencing, trellis frames, and plant support
- Construction and contractor site organization
- HVAC ductwork and pipe bundling
- Facility maintenance and warehouse organization
