The life span of your harness depends on the frequency and type of use. Mechanical stress and friction gradually degrade the properties. UV rays and humidity can also cause accelerated ageing.

Normal duration of use: 10 years.
Warning: This period of use is indicative. A fifth wheel can be destroyed at its first use. A check every 2 years will determine if the product should be disposed of sooner. Between uses, proper storage is essential.

The time of use should never exceed 10 years.
