Type 11, Type 21 and Type 21S are constructed from polymer materials having a flammability rating that has been separately determined by independent testing1. These require a minimum “ HB ” rating according to IEC 60695-11-10, UL 94 or CSA C22. 2 No. 0.17. Additional ratings V-0, V-1 and V-2 are also acceptable.

What is UL Type 21?
They are UL certified Type 21S cable ties, distinguished for their enhanced tensile strength and superior thermal properties over standard cable ties. UV resistant cable ties are suitable for both indoor and outdoor use.
Are Type 21 cable ties plenum rated?
Agency Approvals & Self Certifications Products which are UL Listed as noted in the Typical Data section meet UL Standard 62275 for Cable Management Systems, TYPE 21 or TYPE 21S, and are suitable for use in Air Handling Spaces (plenums) in accordance with Section 300.22 of the National Electric Code.
What is the classification of cable ties?
Cable ties are classified as Type 1, 11, 2, 2S, 21, or 21S, if they conform to the scope of cable management systems as defined by the International Electrotechnical Commission (IEC), Underwriters Laboratories (UL), and CSA in Standard 62275.
Can you use zip ties to support MC cable?
Yes, cable ties are permitted. Section 330.30(A) provides the general requirements and permits cable ties.
Are zip ties NEC approved?
The most common method used to secure and support nonmetallic-sheathed cables is staples but the NEC also allows cable ties, straps, hangers, or similar fittings.
Are all zip ties the same?
Also known as zip ties, they’re fasteners that bundle your cables and wires together to keep them organized and prevent damage. They come in different sizes, lengths, materials and even colors.
Are zip ties plenum rated?
Panduit® plenum-rated Halar zip ties also have a wide range of applications from cable bundling in plenum spaces to nuclear plants and aerospace applications. Plenum rated cable ties also have a low smoke density rating and a very good flammability rating (U.L. 94V-0).
Are white zip ties UV resistant?
GTSE 8 Inch White/Clear Zip Ties, 100 Pack, 18lb Strength, UV Resistant Strong Nylon Cable Ties, Self-Locking 8″ Tie Wraps.
What does loop tensile strength mean?
The traditional measure of the mechanical ability of a cable tie to remain locked around a bundle of wires or cables is its loop tensile strength. The term “loop tensile strength” was first used in the first standard for cable ties, a U.S. military specification for cable ties used in aircraft.
Can zip ties catch fire?
The temperature can range from -40 to 185-Degree F or -40 to 85-Degree C. Large and Long nylon cable zip ties work well for large objects. The cable ties have a flammability rating of 94v.
What are the strongest cable ties?
The strongest Cable Tie that KT provides is the 304 Stainless Steel Cable Tie. KT delivers the industry’s strongest coated stainless steel cable ties and stainless steel banding in a variety of lengths and thicknesses.
How do I choose a cable tie?
The way we measure cable tie strength is by obtaining its tensile strength. Tensile strength is measured in Newton or pounds and is basically the breaking point of a cable tie. The higher the tensile strength, the stronger the tie. Panduit has ties ranging from 18lbs in tensile strength, all the way up to 250lbs.
Where is MC cable not permitted?
MC cables are not permitted to be installed where subject to physical damage.
Can MC cable be exposed in garage?
Type MC Cable without an outside nonmetallic jacket can be installed in an “other space used for environmental air” in accordance with Section 300.22(C). These cables can be installed either indoors or outdoors and in exposed and concealed locations. They can be direct buried, where identified for such use.
Can you zip tie MC to EMT?
you can tie wire FMC and MC to emt I would think if your going to stap it like that you have chosen a path for your home runs and you have built it in a way that you have planned for the extra weight. If you have a pipe run that just runs from point a to point b with min strapping you can not strap to it.
Can flat NM cable be stapled on edge?
Flat cables shall not be stapled on edge. Sections of cable protected from physical damage by raceway shall not be required to be secured within the raceway.
What is the maximum distance permitted between a box and the first strap in a cable installation?
Article 336-18 stated that cable must be secured in place at intervals not exceeding 4.5 feet (1.37 m) and within 12 inches (305 mm) from every cabinet, box, or fitting.
What is the strongest type of zip tie?
Ultra Heavy Duty Cable Ties are the strongest in the industry with the capability of supporting bundles up to 250 lbs. The one piece construction allows for consistent performance and reliability. Available lengths of the Ultra Heavy Duty Cable Ties range from 9”-40”.
How much weight can 4 zip ties hold?
Standard Cable Ties have a 50 lb. tensile strength. Light Heavy Duty Cable Ties have a tensile strength of 120 lbs. Heavy Duty Cable Ties have a tensile strength of 175 lbs.
How many pounds of force does it take to break a zip tie?
Common Zip Tie Tensile Strengths
As a general rule of thumb (and a simplification) here are some tensile strengths that you might find for common zip ties: Standard every day zip ties: around 50 lbs. Wee tiny zip ties: 18 lbs. Standard heavy duty cable ties: 120 lbs.
