What Mount Should I Get?
The Vertical Mount: Attach to any vertical surface. The folding design keeps the cup holder out of the way when not in use. While only TwistLock Drinkware will lock in, the Vertical Mount will also comfortably fit standard-sized cups, bottles, and cans.
The Mini Disc: Attach to any flat surface or inside existing cup holders (such as a side-by-side). The compact size allows you to place it in tight spaces.
The Flat Mount: Attach to any flat surface. While larger than the Mini Disc, it features a tapered edge and a slightly recessed locking mechanism that helps minimize trips and snags.
The Bar Mount: Attach to tubes, raft frames, roll cages, grab handles, bars, or other rounded surfaces between 1" and 2.5" in diameter. The silicone strap and rubber gasket keep your drink secure and upright.
The Recessed Cup Holder: Sized to replace standard-sized drop-in cup holders on boats. It will comfortably fit standard-sized cups, bottles, or cans and lock in TwistLock Drinkware with a twist. Minimum cut out diameter: 3.625"
Each Mount can be used in countless locations. For a more in-depth guide, visit our Buying Guide page.

20 oz Canteen

The Ultimate Canteen.
Designed to fit inside existing cup holders and will lock into any TwistLock Mount with a twist.

Roots in Aviation.
TwistLock was originally designed to add safety in airplanes and helicopters. Then, pilots soon started asking for the same security on their boats, rafts, side-by-sides, and in the rest of their lives.
This system is the answer to a long overdue challenge... there are so many applications (kayak, sports cars, sailboats, aircraft) that typically lack drink holders - Great Solution!
I recently got this Canteen and the Tumbler and they are both high quality and keep drinks hot or cold. Very pleased with this product.
