Review on 🚢 Amarine Made 2pcs Stainless Steel Cup Drink Holder: Ideal for Marine Boats, RVs, and Campers with Convenient Drain Feature by Chris Drury

You are great. 30 and 24 oz Yeti glasses are ideal, as are beer/soda bottles/cans. You will find it very difficult to purchase a 5 3/4 inch drill bit from local stores. This size was not available anywhere in HD, Lowes, Northern Tool or Harbor Freight. fits perfectly in a 5 5/8" hole. It's glove tight so you have to spray some WD40 on the outside and they slide nice and tight. Perfect fit with no sealant or sealant required. I have them in my center console is built in so I had to hose the drains down my residential well to keep water from dripping on my batteries.The hose you need is 3/8" ID.
