Dual Train Horn for DeWalt® 20v Battery (New 2026 Model)
New for 2026: the refreshed Dual Train Horn keeps the formula that made the original a crew favorite — two metal trumpets, one DeWalt® 20v battery, zero installation — and packages it in the latest build. Clip on a pack from the charger bank — the same packs that run your drill and impact driver — and you are holding 130dB of battery-powered signal power.

- Remote module with up to 160 ft of range, plus trigger operation
- Excellent endurance from a single charge
- Handheld use, or secure it to a vehicle when the job calls for it
- Same-day ship-out on every order
From First Pour to Final Punch List
A dual-trumpet air horn hits the sweet spot for working crews: compact enough to live in the cab, loud enough to stop traffic in the yard. Sound the morning start, warn the site before an excavator swings, or give the flagger a signal they can hear over idling diesels. The 160 ft remote lets one person control the horn while their hands stay on the task in front of them.
Because the compressor is built in and the power source is a cordless tool battery, there is no plumbing, wiring, or mounting required — although it will bolt up to a vehicle if you want it there permanently. When the week ends, it goes straight from the gang box to the game.
