Profile by the meter
Extruded customer-specific profile designed parts by the meter. These parts can be made with all established material combinations for a wide variety of applications, for example round cord or square profile.
The profile parts can be supplied either glued or vulcanized. For example a glued round cord could be applicated as an O-ring.
