How is the Adapter Used?
A barbell with 25 mm and 30 mm diameter for spring locks is suitable for retrofitting with the Olympic adapter set. Remove the two spring locks and attach the adapters to the barbell instead. Use the two screws supplied to fix both adapters to the bar. The screws have no heads, so they are screwed completely into the opening until they are flush with the surface. Now you can slide weights with a 50 mm hole size onto the "new" barbell bar and secure them with the spring locks. To begin with, you should tighten the screws in the adapter a little before or after weight training.
Note: The Adapter Sleeve is only compatible with dumbbell bars with a smooth mount.
