The hollow design enables the SAF to be elastically compressed along its cross section (A) when inserted into a canal
previously negotiated with a no. 20 K file (B).

Attempting to expand, the SAF applies light continuous pressure along the entire circumference of the root canal wall.
3. Gradual Expansion

The SAF is extremely flexible and pliable.
It does not impose its shape on the canal but rather complies with the canal’s original shape.
This is true both longitudinally (A)
and circumferentially (B).
The long axis of the canal is kept at it’s original
place throughout the length of the canal
