Fixing rubber chock. D-ring and screw are included in the product.
Fits perfectly
Works.
Spare part to replace the broken one.
Easy to change. Identical to the original.
At first really stiff, but after a week of daily use good.
I exchanged this for an old Chariot cart. Comes with good instructions, the product itself is very similar to what the old cart had.
I replaced this with my bike cart and it works very well!
