Sprayers with spray lock

Continuous Watering Lock

— a device that allows you to fix the trigger (switch) of the sprayer in the pressed position. This is especially convenient for large volumes of work: holding the trigger manually for a long time is rather tiring, and the continuous watering lock allows you to avoid unnecessary stress on your hands.

Note that this feature can be found in all types of sprayers (see the relevant paragraph), including lever ones — many models with this type of action are equipped with both a pumping lever and a separate trigger that must be kept pressed during operation.
