This Stainless Steel Drink Holder - Shallow Drop In style is designed to fit into a hole in the table. Our cup holders can be permanently mounted to the table or remain removable from the table. Because this cup holder is constructed from stainless steel it retains its luster and is both durable and rustproof. Our standard size cup holder fits standard glass bottles and aluminum cans. PLEASE NOTE THIS CUP HOLDER IS VERY SHALLOW. See drawing for sizes.Wrap 1 " wide masking tape around the outside of the cup holder to achieve the desired diameter. We recommend you wait until you receive the cup before drilling your mounting holes.
