Symretie 18" Heavy-Duty Double-Sided Tooth Zip Ties — 100-Pack Black, 120 lb Tensile, UV-Resistant

Symretie 18" double-sided tooth zip ties are heavy-duty, self-locking nylon cable ties with a patented bidirectional tooth design and 120 lb tensile strength, sold in a 100-pack in black.

These 18-inch cable ties from Symretie combine thicker material and an innovative double-sided tooth lock to deliver reliable bundling for indoor and outdoor projects. Made from nylon 66 with UV and weather resistance, the ties are engineered to resist breakage and maintain grip under strain. They come in a bulk 100-pack and include a one-year warranty for added confidence.

How do these zip ties hold up under heavy loads?

The Symretie ties are built to withstand demanding loads thanks to a 120 lb tensile rating and a wider, thicker profile than standard ties. The ─-shaped double-sided teeth share load across both edges, reducing single-point stress and making the lock much harder to strip.

• 120 lb rated tensile strength for heavy bundling tasks
• 0.19" (4.8 mm) width and 0.065" (1.65 mm) thickness for a sturdier cross-section
• Patented bidirectional tooth geometry for improved locking performance

Are these cable ties suitable for outdoor use and varying climates?

Yes — the ties use high-quality nylon 66 formulated for durability in sunlight, cold, and damp conditions. They resist UV degradation, remain flexible in low temperatures, and are water-resistant, making them practical for garden, exterior lighting, and outdoor wiring applications.

• UV-stabilized material to reduce sun-related brittleness
• Antifreeze and waterproof properties for seasonal exposure
• Durable against routine outdoor wear such as snow or rain

What makes the patented double-sided tooth design better than regular ties?

The double-sided tooth system distributes tension across both sides of the strap and engages a movable pawl in the head so the teeth mesh securely. This reduces slippage and increases effective tensile performance compared with single-sided tooth straps.

• Bidirectional engagement creates a firmer, more durable lock
• Integrated molding maintains consistent tooth alignment and strength
• Reduces risk of breakage under repeated or heavy stress

How can I use these ties around the house or workplace?

Symretie 18" ties are versatile for both neat cable runs and practical fixes: from organizing computer and audio cables to securing garden fencing or mounting seasonal lights. Their length and strength let you tackle bundling, fastening, and temporary repairs with fewer ties required per job.

• Manage PC, TV, and home theater cable bundles cleanly
• Secure outdoor string lights, plant supports, and fencing
• Temporary or emergency repairs for hoses, straps, and gear

Who is this for? Symretie 18" double-sided tooth zip ties are aimed at homeowners, installers, electricians, DIYers, and outdoor hobbyists who need reliable, heavy-duty fastening. Choose this 100-pack if you want robust ties that resist weather and strain, work across many projects, and provide a stronger lock than standard single-sided cable ties. Keep them stored sealed and out of children's reach; follow the manufacturer's temperature and load recommendations for best results.
