80cm rubilevel construction level. it is made from extremely light rectangular profiles, without sacrificing resistance, owing to the longitudinal ribs which providegreater structural reinforcement. the base is machined on all models, to ensure a constant accuracy of 0.5mm/m. their three acrylic vials, sealed with epoxy resin, provide high impact resistance, as well as resistance against the negative effects of uv rays, and allow for checking horizontal, vertical and 45° levels. the impact resistant rubber protectors at both ends of the rubilevel construction levels should also be noted. moreover, these protectors are removable and enable professionals to mark in corners and in tight areas
