Never seen one of these offered before. Here's a galvanized metal bracket that came off a retired utility pole in my neck of the woods. Was used to provide additional support to the crossarm, perhaps to withstand the heavy snows that accumulate in this area. Comes with two original bolts and nuts. Note that the end of each side is not showing in the photo. They actually have several additional inches that includes a horizontal bend that conforms with the crossarm.

First email gets this rarely offered item for $25 plus shipping. Will probably have to go UPS due to its large size, or you can arrange to pick it up in person. Here's a nice cgi pic provided by Dustin that shows how it was used in service: [id=481909546] Thanks!
