The air source unit measures 15.2" L × 5.9" W × 12.8" H and can be mounted under the vehicle or along the frame. The Mini Outlaw horn measures 16.5" L × 14.5" W × 11" H, making it ideal for space-constrained installations on heavy-duty trucks.

The Mini Outlaw 127H Train Horn Kit is designed with resilience in mind, featuring weather-sealed construction for both the horn and air system.
