Overview

When a vehicle owner demands a train horn with the ultimate powerful sound, the Wolo Cannon Ball Express Pro truck train horn is what you're looking for. Constructed of all metal, with three (3) trumpets that are triple chrome plated. The horn's heavy-duty mount base is painted bright silver to prevent rusting. Cannon Ball Express comes with a built-in heavy-duty 12-volt electric solenoid. The on-board air system provided is designed to produce a large volume of high-pressure air to power the Cannon Ball Express Pro truck train horn and includes everything necessary for a professional installation. The heavy-duty 12-volt motor of the compressor is balanced to precision, and there are 4 heavy rubber bushings mounted into the base virtually eliminating all vibration. For easy installation, there is an extended length stainless steel high-pressure hose that allows the compressor to be surface mounted, the stainless steel hose connects the compressor to the 2.5 or 5 gallon metal air storage tank. Other features of the Cannon Ball Express Pro are; the tank has a built-in pressure switch, manual water drain, pressure gauge, pressure relief valve and brass fittings. Kit comes with mounting hardware, 10 ft. of flexible high-pressure hose and 20 ft. coiled filler hose with quality brass fittings.
