Stanley 64oz Car Cup Adaptor

Tired of that 64oz Stanley rolling around in your car? Then this is the solution for you! I designed this cup holder adaptor for the 64oz Stanley for my wife, because the both of us were tired of that giant cup flying around in the car/truck. This adaptor will fit any normal sized cup holder. The smaller portion that fits into the cup holder was designed based on the size of the 40oz Stanley, so if you have a 40oz cup that fits in your cup holder, than this will too! The two vehicles in the pictures are a 2022 Chevy Silverado and 2022 Chevy Equinox. Both have been road tested with the 64oz Stanley filled to the top, both hold the cup firmly and securely. If you are looking for something more rugged and extremely durable, please check out our TPU (Flexible) version! Please let me know if you have any questions or color requests! These are made to order, so we can make it in just about any color you would like, even if we do not have it listed. This adaptor is only designed to fit the 64oz Stanley Quencher. It is not intended to work with other cups. Adaptor is not sized to accommodate a silicone boot. If you DO NOT use your Stanley with a boot at the bottom, choose "Normal" size. If you use a silicone boot on the bottom of your Stanley, choose "Oversize for boot". Your adaptor will be made 0.100" larger to accommodate a boot.
