Got three threads with three different subjects. Dallas is ALL 6" vb so let's see it from that perspective. The first pic is a box done right. Not a good pic but a DV100 centered and serviceable from the box. Unfortunately the placement of the boxes by this tree spells future trouble in the second pic. The next pic is two 205s nicely snuggled together. Only one needed service but since it was dug up we repaired both. Should be okay for 10 to 15 years.
