The enclosed lamination dummy (6) provides for the space required for the
upper screw ring in the laminated socket.
• After vacuum forming of the definitive inner socket of ThermoLyn®, grind
away the material covering the vacuum forming dummy until it is flush (Fig.4).
• Remove the 503S3 Screw.
• Put the lamination dummy onto the vacuum forming dummy and secure
with the enclosed countersunk head screw (Fig. 8). The 5Z1 Lamination
