Accessory cord, accessory rope
In this category, you will find a selection of high-quality accessory cords from renowned manufacturers, particularly the climbing brands Petzl and Tendon. We can cut the accessory cord as per meter to your desired specifications. This way, you always get the appropriate length from us. Alternatively, you can also find accessory cords as a complete spool in our shop, which we can offer you at a particularly low price in this case.
What is accessory cord?
Accessory cords are ropes with a small diameter. Typically, accessory cord is relatively low-stretch and very robust. This is due to the construction: Like climbing ropes, accessory cords are made in a core-sheath construction. The manufacturers use different synthetic fibers for the material, such as polyamide or polyester, and high-strength fibers such as aramid, Kevlar, Technora, or UHMWP (Ultra-High-Molecular-Weight-Polyethylene), also known under the trade name Dyneema. The braided sheath is usually made of a very abrasion-resistant material. As a result, you get a thin semi-static rope, which, however, can be a bit "stubborn" due to its construction.
The most common accessory cords have strengths from 4 mm to 8 mm; however, there are also smaller and larger diameters. At Kanirope, you will find accessory cords from 2 mm to 10 mm in diameter.
Accessory cord according to EN 564 or UIAA 102
The requirements of the standard EN 564 or the standard UIAA 102 only apply to accessory cords from 4 mm to 8 mm. The accessory cord available on the market with diameters under 4 mm or over 8 mm is currently not standardized. Accessory cord, which is to be used as part of personal fall protection equipment (PPE), must therefore have a minimum diameter of 4 mm and comply with the EN 564 standard.
Table of minimum strength values of accessory cord according to EN 564
| Nominal diameter | Minimum breaking force |
|---|---|
| 4 mm | 3.2 kN |
| 5 mm | 5.0 kN |
| 6 mm | 7.2 kN |
| 7 mm | 9.8 kN |
| 8 mm | 12.8 kN |
The breaking load describes the force at which an object fails. The amount of force is usually given in kilonewtons (kN). Roughly, 1 kN corresponds to the weight force that acts on a mass of 100 kg. Therefore, accessory cord with a minimum breaking load of 7.2 kN can withstand at least a static tensile load of 720 kg. However, this manufacturer-specified value may decrease in practice due to knots, aging, wear and tear, and past loads.
Accessory cord - Applications and areas of use
Accessory cord is very versatile: Depending on the diameter, it is used, for example, in rope climbing or rope access technology as part of Personal Protective Equipment against falls (PPE). It is often used by mountain sports enthusiasts, high rescuers, and climbers for Prusik loops and especially for secure attachment of equipment. But it is also frequently and creatively used in many other outdoor activities such as camping, flight sports, trekking, yachting, as well as in crafting and DIY.
Our tip: Since accessory cord is somewhat stiff, please pay attention to an adequate ratio of diameter to length. Very short accessory cords are only easy to handle and safe to knot if they also have a small thickness. In general, a minimum length of about 60 cm is recommended from 4 mm diameter. For each additional millimeter in diameter, the recommended length then increases by about 20 cm.
