ANDOLAB Golf Cart Cup Holder for 16.4 oz Propane Heater Bottle

This ANDOLAB cup holder adapts existing golf cart cup spaces to hold a 16.4 oz portable propane heater or similar-sized bottle. The holder is made of PP/plastic and uses a tapered design (5.75" height, 4" inside diameter, 2.6" bottom diameter) to accommodate larger cups and small cylinders.
The listing notes a simple mounting approach: drill a hole in the bottom and secure with a 1/4" x 3" screw and wing nut. The product description cites compatibility with Club Car, E-Z-GO, Yamaha and other golf carts when used as an insert for existing cup holders.
