Datum and Axis Markers RS21
The markers RS21 are installed on an unplastered or unrendered wall to provide a level datum or finish floor level to all tradesmen.
To avoid measurement differences when transferring, the markers have a protrusion to which a ruler can be applied and have a nail hole to allow consistency.
The elastic "stubs" ensure that the surveying measurement is secured until after plastering and easy to find again. Heights and axis are also secured beyond plastering. To avoid possible manipulations, the corners are sprayed over in colour.
After completing all work, the flexible ?stubs? are pinched off - the rework is very little - and the markers remain under the plaster as proof.
We recommend gluing the markers and securing them at least once.
