Kleinn Model 411 Single Round 25" Roof Mount Air Horn, Chrome

Kleinn's Model 411 is a single round 25" roof mount air horn in chrome-plated stainless steel for trucks and SUVs with onboard air. It's universal and gives your rig the long chrome horn look of a big rig.

Included are the 25" horn (25" x 6" x 6"), a 1/4" compression fitting for the underside inlet, and nuts, bolts and washers for mounting. Kleinn rates the 411 at 150.1 dB at 150 PSI.

One long trumpet keeps the roofline clean and still sounds like a big rig. The airline feeds through the bottom of the mounting foot, so it's a good choice on work trucks and show trucks where exposed plumbing would look out of place.

Horn only. Plan on an air system with a 120-175 PSI cut-off, at least a 1.5-gallon tank, a 12V electric or manual pull valve and 1/4" airline. Kleinn requires its 330 roof mount fitting pack for new installs, sold separately. No model-specific install guide is published.

Prefer two trumpets? The Model 401 is a dual round roof horn. For a squared-off look, see the rectangular Model 412. 1-year limited warranty.
