Folks, this is a bit different from other questions so I thought to create a new port rather than tag on to an existing one.
I have just refinished a screen porch which is attached to the house, has a regular roof with shingles and is built on a deck type structure. I had to replace the old rotten support posts which are about 3.5" square and spaced about 2.5' apart. The screen material is in place. I am really pleased with the results. Part of the pleasure of it is the view of the garden but since it is probably 3.5 to 4' off the ground I want to make sure there is a railing. Trouble is I don't want that to mask everything.
I am contemplating putting up horizontal cables that we have seen on other decks. I am just starting to research the systems available but I am assuming I will have to drill smallish diameter holes though the support poles every 4" or so up to a standard height fence cap. The width of the porch is about 11' (5 supports). Does anyone have any thoughts on this? I could revert to regular wooden railings if needed and I think some of the newer cable fencing looks really good.
Incidentally if you are curios the original builder has simply used pine screen doors to wall the porch. They worked OK but rotted eventually and again I am not convinced they provided a strong enough barrier.
