Dovetail Test

The dovetail groove is the joining point of the dumbbells. If it is not tight and strong enough, there is a risk of plates falling off. Our test ensure that one dovetail can bear 200KG weight without being damaged. We also specifically test the dumbbell adjustment rod by continuously moving the adjustment pin back and forth. This ensures a safe user experience without the pin getting stuck during the adjustment.
