Back-Up Alarm for Vehicle Class 3

The Zoro Select 38XF43 is a fixed tonal backup alarm rated for SAE Type C and Vehicle Class 3. It mounts with a bolt and uses a forward-facing speaker housed in gray plastic. The self-grounding option removes the need for a separate ground wire during installation.

Voltage Range and Environmental Limits

Operating voltage spans 12 to 24 V DC, drawing 6 A during use. The IP67 rating confirms protection against dust ingress and temporary water immersion. Sound output is fixed at 97 dB for both minimum and maximum levels, offering no adjustable volume control.

Physical Dimensions and Mounting Headroom

Overall size measures 5 in length, 4 in width and 2 5/8 in height. The bolt mount requires a suitable flat surface and clearance for the forward-facing speaker. Builders needing a smaller footprint, a different SAE type or an adjustable tone will need an alternative alarm.
