If the lower frame of your semitrailer’s backdoor already has holes and you have chosen a lock suitable for the model of your semitrailer, skip steps 1 and 2. If there are no holes in the frame to the right of the handle or the chosen lock is not suitable for this model, please follow steps 1 and 2.
|Place the lock’s body over the door handle and mark the location of the fastening bolt on the semitrailer’s frame.|
|Drill a hole with a 8.5-9 mm metal drill bit. For easier drilling it is better to drill a 3 mm hole first.|
|Place the fastening bolt through the frame, to the right of the handle.
Variant 1. The frame already has holes
|Variant 2. The frame does not already have holes|
|Place the body of the lock over the handle so the fastening bolt goes through the smaller hole in the lock’s body.|
