Ranger II Non-Metallic Casing Spacer

The Ranger II® is an all non-metallic casing isolator/spacer system that uses molded segments to encircle the carrier pipe. Each segment includes at least one molded-in runner and one slide lock. Customer’s may choose from any one of five different size bands to allow correct sizing for carrier pipe O.D. ranges from 0.83″ up to 37.60″ in diameter.

Once sized, the segments are placed around the carrier pipe and cinched together via non-metallic slide locks. Installation is quick and easy while only a small inventory of segments may be used to accommodate a large variety of pipe styles, types and diameters.
