Description

This high-performance kit provides an authentic, powerful train horn sound, suitable for automotive and marine use.

The horn is constructed from die-cast aluminum with stainless steel diaphragms. The air system delivers up to 5 seconds of continuous blast time and recharges from 110 to 150 PSI in approximately 1.5 minutes. All necessary hardware and detailed installation instructions are included.
