If you don't know the force of the gas struts, we need the following information:
1. Type of glider - especially wing tips
2. TOP - GRP or Aluminium Top (in case of Aluminium - insulated?)
3. Year of manufacturing
Please add the information in the comments field please.
If you have doubts, call +49 (0) 5665 407 99 14 please
In Trailers starting from mfg year 2002 you can find the force from the gas strut on the gusset plate on the right side in the Top.
We recommend to order a pair of struts to ensure the same force on both sides.
