Why we made The Knob Blocker - Radio knob guard
Our founder is a member of our local Squamish Search and Rescue team. The idea came after hanging under the long line of a helicopter and having accidentally bumped the volume down to the lowest setting on his radio. This resulted in not being able to hear anything without realizing it, which was a serious safety concern.

The Knob Blocker (Radio knob guard) - Version 1.4
Release Date – Feb 20, 2024
What’s New - channel guard height lowered
What’s fixed - We made the channel knob easier to adjust quickly while using our Knob Blocker.
What’s improved – On previous versions of our Knob Blocker, the guard covered the full front of the channel selector. Changing the channel was achievable from the back side, with intentional effort. We reduced the height of the channel knob guard, so it is easier to manipulate and change channels from the front and back with two fingers. The entire top portion of the channel knob is now easily accessible to grasp with your fingers.
