Threaded lance

A threaded lance is a tube with an external thread meant to be screwed in the pointing head or the nozzle seat of the pointing gun. It is used to fill drill holes and deep cuts in structural elements from the bottom without air entrapment. This is relevant e.g. for the repair/stabilisation with anchors as in this case the uninterrupted bond between structural element, anchor mortar, and spiral anchor is decisive for the success of the measure.
