The standards about the crossarms and terminal parts are in the "Crossarms" page
In urban areas the telephone wires run from roofs to roofs. Before the WWs and their times above all cities were very close spider net.. On the roofs were more place for the wires than on the streets. The roof holders made from steel pipes and L profile steel crossarms with 2, 6 and 10 pins. The 10 pins crossarms were the most common, there were more pins crossarms too, I draw 12 pins ones. I can't draw the all combinations, it is much, you can imaginainate every mixs..

Because of the easier working, the steel pipe has some steel steps.
The most common roof holder type was the 6 pins crossams.
Where the winds are srtonger, the 6 pins crossarms get steel braces
In the bigger urban area are needed more circuits, there are the 10 pins crossamrs used with double pipes. The central Insulators would be far from the pipe for the lineman, because of it the double holder get a wooden path, a plank
On the roof lines are needed terminals too. The terminal technology is same than on the poles.
With braces..
10 pins terminal holders. Naturally here were existed more pins crossams and mixed constuctions, mosty in Budapest. Somewhere in place of the terminal tin channels were used Napoleon Hat terminal Insulators, that is rarer technology.
Somewhere from the roofs run the wires to poles and somewhere were built "Hybrid" terminal poles, the roof holder can be on a wood pole.


Every roof holders have steel anchor wires and rain water resist caps.
