Artigarden Freestanding Garden Hose Holder Hanger, Heavy Duty Metal Water Hose Storage Stand Rack

Does this product have a prop 65 warning?

how many feet of 5/8 inch rubber hose does it hold ?

Could this be used with only one branch for a shorter stand?

What adapter is needed to connect the leader hose from the house water source to the elbow on the back of the stand so the faucet will work?
