Engineered for universal semi-truck and commercial vehicle applications, this massive, heavy-duty roof-mounted configuration allows you to command the road with a deep, authentic, and deafening locomotive-style blast. Designed for clean external mounting on custom or commercial rigs, this high-performance horn kit requires an onboard pressurized air system and can be operated using a manual hand-pull air valve or an electronic solenoid valve. For a proper, leak-free setup right out of the box, the installation requires a Model 330 Roof Mount Air Horn Fittings Kit, providing the ideal balance of gleaming chrome style and serious acoustic presence that serious custom truck builds count on.\u003c\/p\u003e\u003ca href=\"https:\/\/d32vzsop7y1h3k.cloudfront.net\/71aaf76fa76a79979d2455d499a65b3a.PDF\"\u003eInstallation Instructions\u003c\/a\u003e\u003cbr\u003e\u003ca href=\"https:\/\/d32vzsop7y1h3k.cloudfront.net\/4a9c2621e84e07a49b662ea4137c265d.PDF\"\u003eInstallation Instructions\u003c\/a\u003e\u003cbr\u003e\u003cul\u003e\n\u003cli\u003e330 Fitting Pack required if not replacing an existing roof mount horn\u003c\/li\u003e\n\u003cli\u003eManual Hand Pull Air Valve 310 or 311 \/ Solenoid Required\u003c\/li\u003e\n\u003cli\u003eChrome-Plated Stainless Steel Construction\u003c\/li\u003e\n\u003cli\u003eDimensions (in): 25 x 6 x 6\u003c\/li\u003e\n\u003cli\u003eOutput (dB) @ 150 psi 150.1\u003c\/li\u003e\n\u003cli\u003eOne Trumpet 24\" w 1\" Base\u003c\/li\u003e\n\u003cli\u003e1\/4\" Airline Input\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Kleinn Air Horns","offers":[{"title":"Default Title","offer_id":45833873719449,"sku":"KLE411","price":114.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0597\/1227\/4585\/files\/06d959a115cc41eaf530e9ddfdae5f8c.jpg?v=1761572470","url":"https:\/\/battlebornoffroad.com\/products\/kleinn-chrome-roof-mount-single-horn-21-5in-chrome-plated-spun-copper","provider":"Battle Born Offroad","version":"1.0","type":"link"}
