Featuring single rib that makes brackets compatible with both coarse- and fine-profile conduit, PMA® GP Two-Part Support Clamps are designed for use in rail vehicles and vehicles with particularly demanding requirements, as well as wind turbines and other special-purpose machinery. Units offer simplified assembly, with locating pins to lightly hold 2 halves in position. By allowing conduit to turn within bracket, clamps avoid torsion and extend service life.
