Fun with fabrication. I needed a fire extinguisher mount that would put up with off road and still be easily accessible. I kind of copied this from an established design, but with my own modifications. The main frame attaches to the extinguisher with hose clamps. The frame attaches to brackets on the car with a hook on one end and a spring loaded pin on the other. Yah, I could have bought a pre-made mount for $5o, but what's the fun in that.
