This cup holder does more than just hold your beverage – it also holds your cell phone in one convenient spot! Using the SnaptIt Mounting System, this product will fit onto your wheelchair, walker, rollator, crutches, and electric scooter’s handlebars. Featuring an inner ring that folds up or down, this cup holder has been designed to fit both small and large drink containers. Flip the inner ring up to hold things like 12 ounce cans and 20 ounce plastic bottles, or flip it down to hold larger containers like mugs and cans with an insulated sleeve (also known as a coozie). The slot for your cell phone is big enough to fit most flip and smart phones. This cup holder is designed for right hand applications, meaning it should be mounted on the right side of your mobility device – click here for this product's left hand application. Made of high density polyethylene, this combination cell phone/drink holder will last you a very long time!
