175 lb Extra Heavy Duty Zip Ties
175 lb zip ties are the extra-heavy-duty class and the strongest ties in our current range. The figure is minimum loop tensile strength: in a controlled pull test on a new tie, the locked loop should hold at least 175 lb before the strap breaks or the lock slips. Ties in this class are generally wider and stiffer than lighter ties, which is what gives them their rating and also why they feel noticeably more substantial in the hand.

In our catalog the 175 lb class currently includes our 24 and 36 inch lengths, molded from 100% nylon PA66, in Black (UV-stabilized) and Natural Clear White. That pairing is deliberate: long ties go around big things, like 4x4 posts, lumber and pipe bundles, trees and large duct, and those jobs tend to put more stress on each tie. The product grid below always shows the ties currently in this class.
Treat 175 lb as a comparison figure rather than a working load. Real conditions such as sharp corners on lumber or metal, wind, vibration, sunlight and cold all reduce what a tie can hold. Plan working loads well below the rating, use several ties, and never use cable ties of any rating for lifting, hanging loads overhead or anything involving personal safety.

Typical uses
Posts and fence lines
Attaching fence fabric, windscreen and temporary barriers to 4x4 lumber and larger round posts, where wind puts steady stress on every tie.
Lumber, pipe and conduit bundles
Keeping lengths of lumber, conduit and pipe bundled in racks and staging areas. Pad or avoid sharp cut edges that can nick the strap.
HVAC duct and insulation
Closing insulation and positioning flexible duct on larger runs. Where code or the duct manufacturer requires a listed strap or clamp, use that product.
Farm, ranch and nursery
Securing shade cloth, gate signs, tree guards and irrigation supports to posts and pipe across a property.
Is a 175 lb zip tie right for your job?
Choose the 175 lb class when you need a long tie to reach around something large, or when each tie will carry more sustained stress than typical bundling. If your bundles are under about 4.5 inches and the job is ordinary wire management or fencing, our 120 lb ties are usually enough and come in shorter lengths that waste less strap.
If a job calls for more than 175 lb, prolonged high heat, or a permanent fastening in harsh conditions, look at stainless steel ties or purpose-built hardware rather than stacking nylon ties. Our guide to nylon versus stainless steel ties covers where each makes sense.
| Rating | Usual class name | Lengths in our current range | Typical jobs |
|---|---|---|---|
| 18 lb | Miniature | 4 in | Small wires, tags, cords, crafts |
| 120 lb | Heavy duty | 8, 10, 12, 14, 16 in | General bundling, fencing, pipe, cable runs |
| 175 lb | Extra heavy duty | 24, 36 in | Posts, lumber and pipe bundles, large duct |
Do not use 175 lb zip ties, or any cable ties, to lift loads, suspend anything overhead or restrain people. Use rated rigging, anchors and hardware for those jobs.
Frequently asked questions
How much weight can a 175 lb zip tie hold?
Its minimum loop tensile strength is 175 lb, measured in a controlled test on a new tie. That is not a safe working load. Plan real loads well below it and spread them across several ties.
Are 175 lb zip ties strong enough to hang things?
Not for anything overhead, heavy or safety-related. Nylon ties can be weakened by edges, UV, cold and vibration without obvious signs. Use rated hooks, anchors or rigging to hang loads.
What is the difference between 120 lb and 175 lb zip ties?
The 175 lb class has a higher minimum loop tensile rating and generally a wider, stiffer strap. In our current range, 120 lb covers 8 to 16 inch lengths and 175 lb covers 24 and 36 inch lengths.
Are there zip ties stronger than 175 lb?
Yes, higher-rated nylon ties and stainless steel ties exist. Our current range tops out at 175 lb; for higher loads or harsh permanent installs, stainless steel or purpose-built hardware is usually the better route.
