Overview

The 4R108/4R109 Socket Attachment Blocks function as the adjustable connection between a transtibial socket and distal component. The adjustment is done during the trial fitting and secured through the anti-rotation lock of the adapter. After loosening the central countersunk screw, the lower part of the adapter can be shifted against the lamination/vacuum forming shell integrated in the socket by 8 mm medically and laterally in the frontal plane and by 6 mm dorsally and ventrally in the sagittal plane.
