Hi,
I inherited an existing 4" conduit about 200 feet long that has one 90 degree bend. It has an existing 12-strand fiber (currently used), 1x25 pair and 1x50 pair copper, and a pull string.
According to my network admin, the following is a history of how things were installed:
1st pull) 12 strand fiber with string #1 2nd pull) 25 pair copper & string #2 pulled by string #1 (string #1 removed) 3rd pull) 50 pair copper & string #3 pulled by string #2 (string #2 removed)The pull string #3 may be tangled because the string was pulled with the
50 pair copper.I want to install a 1" and a 1"1/2 innerduct. Do you recommend I use the current pull string or try to put in another pull string with a shop vac? Also, what a brand/type of innerduct and materials should I use?
