Antelope manufactures a wide variety of positive (typically hinged) and rigid (typically slip-on) centralizers. These centralizers may be ordered with or without set screws. We recommend running the slip-on rigid centralizers between slip-on stop collars rather than with set screws, to reduce drag by allowing the casing to move within the centralizer as a bearing. We recommend rigid centralizers in 5" length designs to further reduce drag, while maintaining a rigid standoff. The Liner Band (Product 490) is designed to create a positive standoff when running liners, and should be run between slip-on stop collars.
