What Are Cable Ties / Zip Ties?

Cable ties are also called zip ties, tie wraps, or nylon cable ties,  are one-piece permanent fasteners for bundling and securing cables, pipes, and components. A serrated tape threads through a ratcheting head and locks via a pawl-and-rack mechanism. Once closed, a cable tie cannot be reopened without cutting.
The careful selection of raw materials ensure the correct engineering for professional cable ties. It delivers higher tensile strength, rigidity, heat resistance, and chemical resistance .

Chemical Resistance

PA6.6 Cobra Cable Ties® resist: bases oils, greases, soaps, detergents, petroliferous products, clorura dissolvents, alcooli.
Limited resistance to acids. Not resistant to phenols.
For acid-resistant applications: selected sizes are available in polypropylene (PP). Contact Cieffeplast for availability.
Halogen-free materials do NOT contain chlorine or bromine and in the event of fire produce fewer toxic and corrosive fumes, generating fewer acid gases (e.g. HCl). For this reason they are required in the electrical field or in enclosed spaces (tunnels, trains, public buildings).

Packaging and Bulk Supply

Three formats are available to match B2B procurement requirements:
Standard packaging   from 500 to 30,000 pieces per box depending on size. For high-volume procurement, distribution centers, and production line supply.

How to Install Cable Ties and Zip Ties

Wrap the tie around the cable bundle.
Install the cable tie with the knurled surface facing inward and the smooth surface facing outward.
Insert the tail into the head until it engages the pre-coupling tooth.
Verify bundle position (using the pre-coupling tooth with a light pull on the can still release the tie at this stage and for repositioning).
Grip the knurled tail section and pull firmly until fully closed.
Trim the excess tail flush with the head using side-cutting pliers or a cable tie tool.
For installation with a tool: calibrate the tool tension to the specific tie size to avoid over-stressing the material. Cieffeplast installation tools available separately.
Important:  Do not use on body parts.

Cobra® Cable Ties: Sizes and Dimensions

The Cobra® cable tie range covers 31 standard sizes specifically engineered for industrial wiring and fastening. To facilitate technical reference and correct part number identification, our production of black and natural polyamide PA6.6 cable ties is divided into five main families based on loop width:

Light Series (Widths: 2.4 mm and 2.5 mm)

Developed for light-duty wiring and high-precision applications in confined spaces, these variants offer excellent flexibility. The line starts with the micro size 80 x 2.4 mm, ideal for electronics, and extends to standard lengths of 100 x 2.5 mm, 140 x 2.5 mm, 160 x 2.5 mm, up to 200 x 2.5 mm.

Intermediate Section Series (Width: 3.6 mm)

This series ensures superior mechanical strength for securing medium-diameter cable bundles. The 3.6 mm range features five specific lengths to meet every installation requirement: 140 x 3.6 mm, 200 x 3.6 mm, 250 x 3.6 mm, 290 x 3.6 mm, and the longest version at 360 x 3.6 mm.

High-Versatility Series (Widths: 4.5 mm and 4.8 mm)

Representing the most widely used standard in industrial wiring due to their high tensile strength. In addition to the 200 x 4.5 mm size, the 4.8 mm line offers the greatest depth of range. Within this segment, the 290 x 4.8 mm cable tie is the leading solution most requested by engineers, offering the perfect balance between useful bundle length and structural resistance for heavy-duty wiring. To satisfy any other geometric specification, the 4.8 mm line includes short lengths of 160 x 4.8 mm and 175 x 4.8 mm, medium sizes of 200 x 4.8 mm, 250 x 4.8 mm, and 360 x 4.8 mm, up to extended formats of 430 x 4.8 mm and 530 x 4.8 mm.

Heavy-Duty Installation Series (Width: 7.6 mm)

Designed for heavy industrial plant engineering, large electrical enclosures, and the solar photovoltaic sector, these ties guarantee extreme tensile strength. The 7.6 mm series is available in nine lengths to accommodate large bundle diameters: 200 x 7.6 mm, 250 x 7.6 mm, 290 x 7.6 mm, 360 x 7.6 mm, 450 x 7.6 mm, 530 x 7.6 mm, 650 x 7.6 mm, and the extra-long 750 x 7.6 mm version.

Heavy-Duty / High-Section Series (Widths: 9.0 mm and 12.6 mm)

The top-of-the-range solutions for securing pipes, ventilation ducts, or heavy cable bundles in harsh environments. This family includes the 530 x 9.0 mm, 780 x 9.0 mm sizes, and the extra-long 1500 x 9.0 mm variant, alongside the largest section tie in the Cobra® range, measuring 1000 x 12.6 mm.

Frequently Asked Questions

What is the difference between a cable tie and a zip tie?

Cable tie and zip tie are two names for the same product. Other common names include tie wrap, nylon tie, and cable strap. The term zip tie is more common in general purpose especially in North America; cable tie is the standard term in European industrial and electrical markets.

Why are black cable ties used outdoors?

The black cable ties contain carbon black, which absorbs UV rays and slows down the degradation of the polymer when exposed to sunlight. The natural (translucent) cable ties do not contain UV stabilizers, and the degradation process is faster than with the black ones; therefore, they can be used in their natural state outdoors when a long-lasting application is not required.

What does PA6.6 mean in cable ties?

PA6.6 stands for Polyamide 6.6, an engineering-grade nylon. PA6.6 cable ties have higher tensile strength, greater rigidity, better heat resistance (up to +85°C operating temperature), and superior chemical resistance compared to lower-grade or different raw materials. The selected raw material PA6.6 used for Cobra® cable ties is in accordance to class of flammability UL94V2

What is UL 62275 certification for cable ties?

UL 62275 is the international standard for cable management systems, including cable ties for electrical installations. A UL certified cable tie has been independently tested for mechanical performance, flame resistance, and temperature range. Cieffeplast Cobra® cable ties hold UL 62275 certification  verifiable on the UL Product iQ database.

Are Cieffeplast cable ties available in bulk for B2B buyers?

Yes. Cieffeplast supplies cable ties and zip ties in bulk to distributors, electrical wholesalers, OEM manufacturers, and industrial end-users across Europe and internationally. Standard box quantities range from 500 to 30,000 pieces depending on size. Custom packaging and mixed-pallet orders are available on request. Products are consistently supplied in sub-packaging of 100-piece bags and, where applicable, 1,000-piece bags, in order to preserve product quality and integrity.

Key Engineering Features of Cobra Cable Ties® 

Rounded head edges and Radiused inner head corners: larger fillet radii improve tensile strength under load. Reduces risk of head fracture at maximum tension.
Pre-coupling tooth : retains the tail at the head opening before final tightening. Enables one-handed preparation. Prevents the tie from slipping during bundle positioning.
Knurled tail surface : textured finish maximises  grip during tensioning, including with gloved hands.
Flush lateral edges : side walls are level with the rack. Rack teeth do not protrude above the surface. Eliminates the risk of serrated edges cutting into adjacent cable insulation.
Slanted collar on short sizes :  collar slanted in order to easy the fitting and makes insertion easier for smaller diameters

Rounde cable ties’ head to avoid edge in the wiring and radiated inner corners to increase the tensile strenght

The small pre-coupling tooth allows to prepare the ties to be closed, avoiding to get it unstrung. Rough surface to easy handling

Knurled surface to easy handling while you begin the traction

The lateral edge are high as the rack to avoid cutting the cables

Short sizes have the small collar slanted in order to easy the fitting
