FAA Advisory

Click here for FAA Advisory Circular #70/7460-1M (Nov. 2020)

Redball Applications

While the FAA advises that 36" power line markers be used on high transmission lines and hazardous river crossings, smaller 20" power line markers are permitted on less extensive power lines or on lines below 50 feet in approaches to airports. Available in 9" and 20" diameters, Redball power line markers (formerly Redbell) are an economical solution for satisfying the FAA advisory for smaller power line marker applications and have been used for many years by hundreds of utilities. International orange, white, and yellow colors available.

NOTE: For larger size power line markers, greater durability, higher voltages, bigger lines, or more demanding applications, our various SpanGuard markers should be used.

Easy Installation

Exclusive TygrGRIP rubber strips are used to firmly hold the marker on the line. The rubber is wound around the line to a 1" diameter, and the halves are bolted together, clamping the TygrGRIP firmly onto the strands.
