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.

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!
