Kleinn Quick Connect Coupler Relocation Kit

This thing is just what I was looking for.

I only wish it was a little cheaper, all I got was the bracket some fittings and some tubing, I still had to go out and buy the air hose fitting so I could hook up my air line. But it did the job. Just what I needed. View more reviews...

Kleinn Air Tank

Klein Air Tank

I haven't installed this tank just yet. I received delivery just last week. Anyhow, I bought this tank to replace the tank that came with my Air Horn System. The tank that came with the Horn Kit was very thin and didn't hold up very well. But, just looking at the Kleinn tank I can tell it is of heavier design and seems to be well made.
