made from seamless steel pipes, the gripping force is
applied by one row of Set Screws. The outside ends of
these collar are generally tapered to a degree which
helps to hold the centralizer and avoid the ends to
hit the Bows when the centralizers are placed over them.
They are available in all sizes ranging from 2 7/8" to 20".
