The kit comes complete with everything you need to convert your standard air horn into one with a pull chain. 

The kit comes complete with:

• Air Line Tube
• Valves
• Reducers
• Mounting Kit
• Metal Pull Chain
• Connectors

Please Note: This pull chain kit will NOT enable you to fit an air horn. You must purchase a Hadley Air Horn fitting kit to fit your horn. If you already have a genuine Hadley air horn fitted then this kit is all you need to add a pull chain.
