Common Questions

Can I Use My Own Cup?

The Vertical Mount and Recessed Cup Holder both will comfortably hold any standard-sized cups, cans, or bottles, however, only TwistLock Drinkware will lock into them.

The Flat Mount, Mini Disc, & Bar Mount only work with TwistLock Drinkware.

Is the Drinkware Insulated?

Yup! All TwistLock drinkware is stainless steel, double-wall vacuum-insulated. It will keep your drinks hot or cold for hours.

What If My Boat Has Carpet?

If your boat has carpet, you can still install the mounts using the included screws.

How to Install the Flat Mount

The Flat Mount includes x4 double-sided 3M VHB adhesive squares and x4 self-tapping screws. Either method provides a secure hold.

Where Can I Use It?

Pretty much any flat surface. Some favorite uses include:

  • Paddle Boards
  • Fishing Boats
  • Cooler Lids
  • Raft Gear Boxes
  • Riding Lawn Mowers (Fenders)

What's the Difference Between the Flat Mount and Mini Disc?

While both Locking Bases can be added to nearly any flat surface, the primary difference between the two is their size.

The Flat Mount is a bit larger (diameter: 4.50") and features a tapered edge and a slightly recessed locking mechanism that helps minimize trips and snags.

The Mini Disc is smaller (diameter: 2.655"). The compact size allows you to add it inside existing cup holders, tight spaces, and nearly any other flat surface.
