Joint protection blocks are assembled in both trihedral and tetrahedral stanchion. There is a possibility of one- and two-channel JPB manufacturing. Conducted tests and working experience have shown that JPB stably functions under thermal conditions from -60 0C to +60 0C without losing its functional characteristics.
