Value Pack: 120 pieces per pack - Black, length x width: 200mm x 3.6mm. UL 94V-2 flammability, strong tensile strength up to 18kg (using two or more at the same time to improve tensile strength). Please do not break it with bare hands to avoid injury, use scissors to cut it. Very Strong & Durable: The heavy-duty zip ties are made of industrial strength nylon 6/6, with strong tensile strength, durability, oxidation resistance and a high degree of climate adaptation. Works well in extreme conditions (-25C to 80C), normal service life up to 6-8 years.Vacuum packaging further reduces oxidation ability. Easy to Use & Locking System: Smooth ends ensure easy insertion into the lock. No expensive tools required. The locking system is very reliable, the deep tooth design allows the hard locking head to produce a satisfying click and lock it firmly in place. The locking teeth will stop the cable tie at the desired length and you can snip out the excess cable tie to make it more secure. Economical & Reusable: If you are not ready to finalize the installation or forgot "one or more wires", there is a release tab on the lock head, you can press the tab to release the cable tie, then use it again. (We always recommend that you cut it off and use a new one because the tie head is relatively small, you may be a little difficult to operate with your thumb.) Strong DIY Ability: Whether organizing a home office or project around the house, doing small home renovations or a commercial construction job, the cable tie set will help you. Organizing electrical and laptop cords, securing suitcase zippers while traveling, hanging lights or streamers, securing bicycle accessories, securing a fence and much.
