Troy Aerobic Pac - Roulettes pour support d'accessoires - MDR-CAST

The set weighs a solid 15 lbs, so you can tell they're built to handle real weight without wobbling. I swapped out the stock wheels and the rack glides across the gym floor now, no more dragging or scraping.

Finally got these mounted on my accessory rack and they roll smooth as butter, even with all the weight loaded. The 15 lb shipping weight felt sturdy when I unboxed them, and they lock in place exactly as intended.
