تروي أيروبيك باك - عجلات حامل الملحقات - MDR-CAST

Was a bit skeptical about casters this heavy-duty being needed, but the 15 lb. weight of this set tells you they're built to last and they handle the loaded accessory rack exactly as promised. Rolled it across a carpeted threshold and it didn't even flinch. Pinned them on in about ten minutes total,

Bolted these onto the MDR-VPAC rack and the 15 lb weight tells you they're solid steel, not the cheap plastic ones. The wheels roll smooth even on my garage's rough concrete floor, which is exactly what I needed for moving the whole unit around.

Swapped out the factory casters on my MDR-VPAC and these bolt right on with zero fuss, the 15 lb set feels built to last. They roll smooth even over a slightly uneven gym floor, which is more than I expected for accessory rack wheels.
