37448 Spirit Level, 48 in L, 3-Vial, Non-Magnetic, Aluminum, Yellow

STABILA levels are unparalleled with regard to their accuracy and dependability. The secret - the vials made of block acrylic glass are firmly epoxy-locked in the frame. A ideal system. The vial is firmly cast in the high-strength aluminum frame with non-shrink epoxy. No re-adjustment, no realignment, no tensioning against springs made of steel or fatigued plastic, no welding or clamping stresses. Just as accurate after 10 years as on the first day.

• Every level is electronically adjusted, then accuracy inspected and certified
