FIELD: oil industry.

SUBSTANCE: invention relates to the oil industry, namely to a protective barrier of a drive of a rod borehole pump. Protective barrier 9 for a head of a balancer of a rocker machine contains two interconnected panels 10, 11 with the possibility of removable fixation to rack 4 of the rocker machine. Panels 10, 11 have a U-shaped cross-section, and they are equipped with longitudinal grooves 12, 13 and made of plastic material. In an upper part of panels 10, 11, slots are made in the center, providing passage of the head of the balancer during operation. In upper and lower parts of barrier 9, panel 10 is equipped with transverse grooves 15, and panel 11 is equipped with holes 17 made opposite to grooves 15.
