This bracket I purchased from John Hall. It is the mid-span version. It would be strung between two sets of trasposing lines to keep them apart. I have used the glass type and rubber type (made by Contenental Rubber Works) for display. There is one bracket I want to get yet and that is the one which uses regular pin types. Usually it was Whitall Tatum or Hemingray CD 154's. Hope you enjoyed these pictures. Take care stay safe and be well to all.
