Roots in Aviation

The Flat Mount Locking Base was originally created to provide a secure drink holder on the floors of Helicopters. The slightly recessed locking mechanism and rounded corners make this mount ideal for locations prone to tripping or catching things.

This Locking Base has become a favorite for paddleboarders, boaters, and outdoor enthusiasts.

Great Products!

We love these products. They installed easily on our raft and feel super secure. I love that I won't worry any more about my drink being knocked over by the dog or an errant wave. Highly recommend.

Hold my beer

Gone are the days when I had to ask someone to hold my beer. These are awesome and work great. I like how small the little locking pucks are; they are very unobtrusive and fit in places no other cup holder could.
