As you can see there are two separate pieces and they were slipped onto the tops of their crossarms. Once the desired spacing or "fit" was achieved, a bolt/nut joined them together. There also is a small hole in the sides of each for a nail to further to secure these "buck arm" crossarm spacers.

They are embossed with Fletcher lettering and appear to be teens or thereabouts. Several sets of these were located on the Hingham MA Municipal Lighting Plant system during a town-wide conversion of poles, wire, crossarms, transformers, etc., to accomodate a higher primary distribution voltage during the late 1980s. I was lucky to get hold of these. The old timers at the utility said there weren't too many of them left in the air at the forementioned time but added there once were more around town in prior years.

I haven't seen these in any Fletcher catalogs but I'm sure they were listed. Does anyone have a documented age span for these. I've never seen these brackets anywhere else.

In addition to the vintage images of the Hingham town utility I have been sharing here, I will be posting photos in the near future of unusual and interesting line construction items/artifacts they used. Many of these artifacts will directly relate to the history and fokelore I have been adding about this interesting electric utility I grew up with. Links cross-referencing such photos will be included.

FYI... The half on the right is slightly bent where it slips over the crossarm.

Three more photos/views of these are posted. Click "Next" after each one.
