Screw - Cross back 3A
Concerning: Etac Cross 5, Cross 5 XL
We replace the screw to the lumbar joint of the Cross back 3A. When tightening the screw with a higher torque than prescribed there is a risk that the joint breaks. The new screw is 2 mm longer than the previous one, this allows the joint to withstand a higher torque when tightening the screw. Screw M 6x 18 MC6S (11670) is replaced by the screw M 6x 20 MC6S (11684). The new screw fits both new and old 3A back supports.
