VEVOR Pool Rail 32x23 Pool Railing 304 Stainless Steel 250LBS Load Capacity Silver Rustproof Pool Handrail Humanized Swimming Pool Handrail with Blue Grip Cover & M8 Drill Bit & Self-Taping Screws

Does this have grounding cups that are made for the pool rails ? pool inspector says he needs to see

Are the mounting bolts and accessories rust proof?

Can this rail be attached to a wood deck and not damage the wood deck when used and can you use just one. It will be used for stepping out of a hot tub onto the deck. The deck is even with the top of the hot tub. Thank you
