The K5LA Provides The Most Efficient Sound Amplification Possible!
This is quite possibly the loudest thing we have ever heard! The 5 aluminum kettle-drum bells and dual-disk diaphragms produce the loudest, clearest, locomotive horn sound possible! They sound with as little as 60 PSI
Highest Quality Construction Provides Years Of Train Horn Fun!
These horns are amazingly loud and will stay that way for years! Constructed of a die-cast manifold and bells with pre tuned single piece bell housings the K5LA is one of the most durable horns built.

This is a one of a kind sound in the air horn industry and makes this horn one of the most stunning horns around!
The 5 bells of the K5LA can be easily reversed for signaling in both directions and provide many installation possibilities! The aluminum finish is easily polished or powder coated for year of good looks and great sounds.
