Bar-Lok zip ties outperform just about anything the competition has to offer, with the highest tensile strength per cross-section of any leading brand of zip tie. Bar-Lok ties offer virtually no creep; they will not loosen or relax, even under extreme heat, humidity and/or vibration. They are also lighter, more flexible and they are incredibly resistant to the damaging effects of petrochemicals. These Bar-Lok cables ties contain 2% carbon black and the temperature range is -40° F (-40° C) to 176° F (80° C). They are manufactured from type 6/6 Nylon, which is used because of its impact strength and resistance to abrasion and chemicals. Bar-Lok nylon ties are constructed of a weather-resistant 6/6 nylon resin. They are designed for both indoor and outdoor applications because they have greater resistance to ultraviolet light are weatherproof and impervious to the elements. Bar-Lok nylon cable and wire zip ties by Avery Dennison are used in industries and applications such as electrical, electronics, CATV, HVAC, transportation, telecommunications, packaging, retail, beverage and automotive. Bar-Lok zip ties are used for everything from bundling wire and cable, to packaging, security-tagging, mounting, temporary repairs, and countless other uses around the house, at work, or in any industrial setting. USA made Bar-Lok zip ties by Avery Dennison are high performance nylon wire ties that resist extremes of temperature, UV light, vibration, humidity, and salt. They survive cyclic shock fatigue up to 70 percent longer than most competitive ties and they’re unaffected in applications where most types of grease, oil and fuels are present.
