Much used in streets, sidewalks, curbs, gutters, parking lots and industries, the grills in the PMSP GR 135 pattern from Fuminas are also available with FE 50007 nodular cast iron in the CL D400 and E600 endurance classes. Traditionally known in the market as "wolf mouth" or "lion's mouth" grills, they are compatible with rainwater collection wells, preventing the passage of debris that can cause flooding. Non-slip, reduce risk of accidents (as required by NBR 10160). They also have a fused pin locking system that avoids theft and breakage.
