Kleinn Air Horns 230 Black Triple Train Horn is the Beast for everyone who told that they wanted a louder, nastier train horn. Three tuned trumpets, 17-1/2-inches, 14-1/2-inches and 11-1/2-inches. High impact ABS. Flat rack design requires 40-percente less clearance than the 500 series train horns. Trumpets can be separated from the mounting brackets for installation in vehicles that could not otherwise fit full-size train horns. This model can be upgraded with the BlastMaster upgrade kit to make it go even louder. Too Loud? Too Bad.
