Just finished 4 Anchor Float Ring Assemblies. These are made of 3/8in. Stainless. These won't elongate like the cheap 5/16 ones when floating a heavy Anchor and chain. The snap is 3/8 stainless also. A safety line is attached so you can't loose ring overboard. All you need is a buoy big enough to float your Anchor and chain. $40. Each PM or Reply if interested.
