4 Function

The device comprises a housing assembly which contains a spring component that allows the
Pyramid Tube to deflect and/or rotate through a limited range under an axial and or torsional
load. When the load is removed the spring returns the Pyramid Tube to its original position. The
effect of this movement is to attenuate any shock forces that would otherwise be transmitted to
the stump socket interface both in axial and rotational directions.
