Adapter to be used for guiding bolt into plaster anchoring disk, comprising lateral bore for securing screw

摘要

The bolt has to be guided through a bore in the center of a disk used as a support for plaster cast to a concrete wall and is manipulated by a pneumatic device. The neck of the device can be inserted into the central bore (1) at a shallow cylindrical adapter. The adapter is provided with a circular sleeve (5) extending into four radial positioned grooves (6) complementary to the shape of the anchoring disk to be joined from below. The adapter is secured to the tool with a screw inserted into a lateral bore (3).
