rust 4-rod made to measure
well grate with 4 stable rods D 16 mm
4 rods give a symmetrical image so that water jet can dip in the middle of the rods.
The rods are located on the right and left of the well trough wall each 50 mm.
The flat strips protrude 30 mm downwards, so a slight movement in the trough is possible and completely removable.
