J.W. Winco Stainless Steel Adjustment Plate with Bulls Eye Level 30mm GN2277.1

GN 2277.1 adjustment plates are used in combination with GN 2277, Type A bull's-eye levels with mounting flange for bolting to surface. The mounting bore holes offset by 120Degree allow the bull's-eye levels and the mounting plate to be aligned in relation to the mounting surface. An alignment ball at the bottom surface of the adjustment plate serves as a tilting point. Specific tightening torques of the bolts are allowed to be achieved, so that the bubble is centrally located inside the marking ring once the horizontal alignment is reached.
