Low-Cost, All-Purpose Carsonite Markers for Utility Cables & Pipelines

Carsonite Utility posts for marking buried lines and cables.  Available from www.berntsen.com

The primary function of the above-ground Carsonite pipeline markers is to identify the location of utilities and alert those who might be working in the area. 

In accordance with the PHMSA, underground pipelines should be marked with permanent pipeline markers in a "line-of sight" fashion to indicate presence and location. When marking utilities, the posts should also carry the type of pipeline (ex: natural gas ) and contact information of the company that operates it.

Carsonite Pipeline and Utility Markers

Carsonite is the perfect choice for high visibility and easy identification of underground utility lines. This trademarked three-rail design combines structural integrity with above-ground flexibility, as well as protection for decals. They’re easy to install and lightweight for ease of transportation.

Post anchors (sold separately) make it virtually impossible to remove the posts without proper equipment. The marker is highly resistant to vandals, with special composite material that will survive multiple small-caliber gunshots without significant loss of legibility or damage to the post. Our 6’ models weigh 2.9 lbs., and they’re sold 20 per case.

Installation is made easy in almost all types of soil without the need for a pilot hole. The RMTLPDR1 installation tool can be used for this purpose.
