Abstract

A leveling spacer device for laying sheet shaped products for the covering of surfaces, including a base, which may be positioned at the rear of a laying surface of at least two sheet shaped products being adjacent and placed side-by-side relative to a side-by-side direction, a separator element rising from, and perpendicular to, the base and configured to slide between the facing side walls of the two sheet shaped products placed side by side, a threaded stem rising from the separator element with a screw axis orthogonal to the base, a presser screwable onto the threaded stem and an anti-sliding protection ring interposable between the presser and the base. The protection ring includes a first surface facing towards and configured to contact the presser and a second opposing surface facing towards the base. The second surface has a sliding friction coefficient greater than a sliding friction coefficient of the first surface.
