Product details
The Kleinn HK7 ProBlaster Train Horn Kit features "The Beast" Model 230 black ABS triple train horn on a flat rack mount, utilizing three tuned high-impact ABS trumpets measuring 15, 13, and 11 inches in length with a base that adds an additional 3.5 inches. Requiring 40% less clearance than other full-size train horns, the trumpets can be separated from the bracket for a much easier installation in tight vehicle spaces that otherwise couldn't fit full-sized horns. This comprehensive package includes a complete onboard air system featuring a 150 PSI 100% duty cycle waterproof air compressor, a 3-gallon steel air tank internally coated with Cortec against corrosion, a bonus tire inflation kit with a storage bag, and all necessary hardware for installation, while offering enough power for your horns, air bags, or small air tools, and the flexibility to be upgraded with a BlastMaster valve upgrade kit (P/N 6885). ProBlaster complete 230 ABS triple train horn package with 150 PSI 100% duty-cycle sealed air system. Kleinn Universal Beast Train Horns / Onboard Air Kit - 3-Gal Tank - 150 PSI
