How to Choose for Your Vehicle
Always measure the depth and diameter of your console holder. Look for an adapter with a rubberized twist-lock base rather than simple friction pads for the firmest grip.

The Seven Sparta adapter ends cup tipping forever. It grips your console like a vice and securely holds your 40oz tumbler with its handle perfectly positioned.
