Rhino TriView™ Extension

In many areas, markers over 8 feet in length are needed to mark facilities. Heavy snowfall, tall growing crops or other vegetation can obscure the visibility of these facilities, making them vulnerable to damage. Shipping and installing extra-long posts is difficult and expensive, so we found a solution: the TV Extension.  It comes in two parts, which saves cost on shipping and makes installation easier.

Available Lengths: 108”, 120”, 132”, 144”
