I am about to install 4 T-105s, for a house bank, and the best, shortest
route to the inveter for the cables, is down the outside of the battery
box for the +ve, and under the battery box, to the inverter.

Is there any reason *not* to run the cable under the battery box (the
box is up on a short platform, sitting on a sort of shelf, with
clearance for the cable to be clamped to the side of the bulkhead the
battery box is attached to) The battery box is a fully covered/enclosed
USCG approved one, if that makes any diff.
