Our Brass Jumbo Drop In Drink Cup Holders are tapered to hold your drinks secure at your poker table without spilling. This 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 Anodized Brass it retains its luster and is both durable and rustproof. 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.
