Professional-Grade Safety with Customizable Volume Control

The Pollak 41-761 Manually Adjustable Back-Up Alarm is a premium safety solution engineered for heavy-duty vocational vehicles, construction equipment, and commercial fleets.

Built to endure the harshest conditions, this alarm is housed in high-impact, non-corroding plastic that is both weather-resistant and steam-cleanable. Its solid-state electronics and adjustable volume make it a versatile and reliable choice for any heavy-duty application.
