Abstract
A cavity wall which is usually made with a hollow concrete block as the inner wythe and brick as the outer wythe is disclosed. A special purpose insertion tool is fitted to a standard hammer tool. A center pin is provided in the insertion tool made with an indent to match the pointed end of the tie. The pin is then pressed into the SDS fitting which is the connection into the drill. The tie end is supported by a short sleeve which, when it contacts the face of the wall, retracts against a spring until the tie driving is completed. A modified embodiment of the adapter recognizes that the tie when activated by the hammer invariably rotates clockwise. Accordingly, if the spring is wound clockwise, the bottom tail end will dig into its seat. On the other hand, if it is wound counterclockwise, it rotates in a 'tail skid' relationship to the seat.
