Heavy Duty Trigger/Clutch for Battery and Manual Sprayer Lance

This heavy-duty trigger/clutch is a replacement control component designed for compatible battery and manual agricultural sprayers. It allows the operator to start or stop liquid flow through the sprayer lance by pressing and releasing the trigger.
