The top is a natural wood product. Knots are repaired, spots may exist on the underside of the top. The tops must be stored horizontally, on a flat surface, in a dry place, protected from the weather and covered on both sides. Changes in air humidity must be avoided. The beech worktops cannot be mounted with a sheet steel covering as this may cause the worktop to warp.

The respective threaded inserts (pre-assembled)/fastening material must be ordered for each substructure
