The RhinoDome Test Station™ from Pro-Line is engineered for exceptional durability and functionality in demanding outdoor environments. Constructed from proprietary RhinoPolyAE thermoplastic, this test station features a robust design that ensures reliable performance across a wide temperature range from -40°F to +150°F. The 3.5-inch outside diameter post, equipped with a 10-inch anchor tube, secures firmly into the ground, while the 21-inch dome topper and removable cap enhance visibility for identification purposes. With a commitment to longevity, the RhinoDome is designed for over 10 years of outdoor service, supported by a 10-year warranty. Its industry-standard 11-hole terminal board is convenient for various applications and comes standard with two terminals. Marking and locating capabilities are further improved with hot-stamped one-color graphics prominently displayed on two locations, ensuring clear communication for utility environments such as construction sites, pipelines, and utility conduit systems. Additionally, it's retrofit-ready, offering compatibility with existing RhinoDome accessories to maintain functionality over time.
