What is the weight capacity of this garment rack?

The total weight capacity is 70lbs.

Do the wheels lock on the GAR-01506 garment rack?

Unfortunately this specific item does not have locking wheels, but several of our other garment racks do, including the one below that also comes with additional shelf space for added storage.

Is there a cover made to fit this GAR-01506 garment rack? Thank you.

The only garment rack cover we carry is only compatible with GAR-01120.
