Euro Joe ダンベル交換用スペーサー

The fact that any of these three spacers fits across all three dumbbell sizes is a lifesaver when you've lost one mid-workout. They click into place snugly and hold up fine during heavy sets. Just wish they came in a pack of five for backup, but three does the job.

The three spacers are all identical in size, so I can swap them between any of my dumbbells without fiddling around. They click in snug and hold tight during a workout, which is exactly what I needed after one got bent.

Lost a spacer during a move and these three replacements fit perfectly across my different sizes. The plastic feels dense enough that I'm not worried about them cracking under regular use. Glad I could get just the spacers instead of buying whole new dumbbells.
