I ordered two rim locks. Easily on the trailer. Unfortunately, the lock can not be operated at verbautem vibration caravan (in my case Winterhoff coupling), it can not be far genung defer and finish. That it is better to include in the description, the order and Make a return saves a lot of avoidable costs for everyone involved! The castle depends unprotected outdoors, but if you used a drawbar anyway guard, that does not matter. Otherwise, this is a deficiency. Because of the lack of reference in the description and the unprotected lock position 2 stars.
