• The markers RS10 and RS11* are used to secure survey points on construction sites without plastering work and in door or window reveals.
• To secure axis permanently until the building is completed, the markers are already measured and fastened in the slab formwork or the slab edge formwork on axis.
• The negative imprints, which are clearly visible for all trades, are used for the dry wall construction and any further inside installations. 
• The foreman uses the negative imprints at the ceiling edge to transfer the axis right to the freshly concreted ceiling with a string (chalk line) or laser. If required, they can later be used to install the façade.
• The RS10 & RS11 Datum Markers are also available in red without the inscription “Meterriss”. Article no. RS10r oM. and RS11r oM.
