Item see fig. 5
To fabricate the prosthetic socket for the 3R78=KD, observe the section "Fabricating the pros­
thetic socket" (see Page 25).
Position the lamination anchor or socket adapter so that all prosthetic components between the
socket and prosthetic knee joint can be connected to each other correctly.
Join the prosthetic socket and the prosthetic knee joint using the adapters you selected.
Be sure to follow the adapter instructions for use during adjustment and installation.
Position the 743A80 50:50 Gauge on the anterior side of the prosthetic socket and mark a point
respectively in the distal and proximal area.
Using these points, mark the anterior centre line of the prosthetic socket.
Clearly mark the anterior socket reference point
