Model 52 resonating horn is ideal for penetrating high ambient noise levels. Being electrically-activated, Model 52 does not require an expensive air compressor for operation. It is able to withstand the shocks, vibrations, dust and atmospheric conditions encountered in off-road use.

Rubber gaskets and a power connector make Model 52 completely watertight. The projector and internal parts are made to resist corrosion; the exterior is sealed with gray enamel paint and the housing is die-cast aluminum. Model 52 has a duty cycle of five minutes on and five minutes off.

Used by many major manufacturers of construction equipment, Model 52 resonating horns suit the warning needs of any off-road vehicle working in a high noise environment.
