P.L.M. Products

An aerial spacer exists with this company's name on it.  The marking on the insulator and the patent record indicates the company was in Cleveland, OH.

As of December 9, 2003, Raymond G. Horrocks still lived in Cleveland, Ohio.  I talked to him on this day but his memory was hazy.  Mr. Horrocks was the president of the company.  He indicated that the aerial spacers were manufactured by some other company but that PLM Products sold "quite a few of them."   Besides the pink aerial spacers, "some of them were gray."
