Line Insulators for Round Posts and 2" Polytape
Insulators 07-90 and 07-91 screw onto round posts up to half an inch in diameter and hold polytapes up to two inches wide roughly two inches out from the post. Products 07-41 and 07-42 can be applied to wood or fiberglass posts (including one-inch or two-inch fiberglass posts) with nails, screws, or nuts and bolts. Nails included. They can accept almost any polyconductor–polytape up to 2 inches wide, any sort of polywire, and polyrope up to half an inch thick. Being attached to the post at two points, they carry the conductor between half an inch and an inch out from the post. Both insulators are available in white and black.
