Injection plug VS is applied to the extension of the mixer nozzle to obtain a good filling of the Chemical Anchor in larger drill holes.

In order to make an approved installation according to the CE marking for the Chemical Anchor ESSVE ONE and ESSVE HY, it is assumed that the VS injection plug is used to obtain the load values ​​and safety factors given in each ETA document. VS injection plug is required for all installations where the drill hole is 18 mm or larger if the installation is upwards, or if the mounting depth is 250 mm or higher for horizontal or downward mounting.

The figure after the designation VS indicates which dimension the drill hole has. Thus, the injection plug VS18 must be used for Ø18 mm boreholes.
