Here is a picture of Accessories Mfg. Co. Chicago, IL. Besides being sold on there own they were distributed by Sears and Montgomery Wards in their farm catalogs. I was lucky enough to find a display for the Leverlox gate system showing how it was to be used. On the far left is the Gate anchor insulators made by them not to be confused with the ones on the Leverlox system they are different. And also is the many copied Twin Toweres lightning arrester for fences. Dare, Fi-Shock, Zareba have all copied this design and is now made in China.
