Universal connector for attaching Styrofoam and wool. Short expansion zone. Thanks to the new construction of the expansion zone, the connector can be installed in all categories of substrates while maintaining all strength parameters! The head of the metal pin is covered with plastic, low point thermal conductivity. Stem design prevents stem corrosion, sealing collar. The increased number of glue "pockets" on the pressure flange allows for better adhesion of the adhesive mortar. The design of the T-shirt increases the stiffness of the pressure collar.
