Add a locking cup holder and secure your drink with a twist! The Flat Mount's tapered edge and slightly recessed locking mechanism minimize trips and snags—making this perfect for paddleboards, boats, rafts, or nearly any other flat surface.

Installation is easy—use the included self-tapping screws or ultra-strong adhesive to mount it wherever you need.

Paired with the double-wall vacuum-insulated tumbler, your drink stays hot or cold for hours—because the only thing worse than spilling your drink is drinking it lukewarm.

Only Obsidian Black drinkware features the engraved 'TwistLock Beverage Locking System' logo, as shown. The other colors do not.

This is the best system I've found for my boat. It was easy to install and works great. The can cooler is very insulating and the locking base works as advertised.

I was given a system to try out and it works great for our use. We have it mounted on our tractor and it’s perfect for long days working. Super handy!
