The manufacture year is identifiable by a colour fibre indicator inside the rope. If the need arises to determine the accurate age of the rope, the end of the rope may be cut open and the colour (fibre) indicator shall be consulted to determine the year of manufacture.
The following is a key to the colour marking of the year of manufacture (this only applies to dynamic ropes produced by LANEX – different rope manufacturers use different colour identification systems!):
| Year - Colour | Year - Colour | Year - Colour |
| 1990 - red / blue | 2005 - blue | 2021 - green / yellow |
| 1991 - red / green | 2006 - yellow | 2022 - black / yellow |
| 1992 - red / black | 2007 - black | 2023 - red / blue |
| 1993 - green | 2008 - red / yellow | 2024 - red / green |
| 1994 - blue | 2009 - blue / yellow | |
| 1995 - yellow | 2010 - green / yellow | |
| 1996 - red | 2011 - black / yellow | |
| 1997 - red / yellow | 2012 - red / blue | |
| 1998 - blue / yellow | 2013 - red /green | |
| 1999 - green / yellow | 2014 - red /black | |
| 2000 - black / yellow | 2015 - green | |
| 2001 - red / blue | 2016 - blue | |
| 2000 - black / yellow | 2017 - yellow | |
| 2002 - red / green | 2018 - black | |
| 2003 - red / black | 2019 - red /yellow | |
| 2004 - green | 2020 - blue /yellow |
The colours of the indicators are repeated in 11-year cycles.
If you have any doubts regarding the age of the rope, send us an approximately 20 cm long sample taken from the end of the rope. We will provide an accurate identification of the rope for you.
