GN 350.3 Spherical Levelling Washer

Spherical levelling washers GN 350.3 have been designed to match the levelling sets GN 350, GN 350.1, GN 350.2 and GN 350.5. The two spherical washers are used together „undetachably“. The load bearing capacity of these spherical washers is relatively high. This is not only due to the material quality but also to the matched sphere of the concave „pan“.Furthermore it is recommended using high-strength washers for bridging d2.
