No one has mentioned rope noise.
If the guide extends down to the ringing room ceiling it can act as a
noise shoot and generate more rope noise than is acceptable.
This is easy to fix.
25mm holes in the pipe, on 2 sides spaced about every 150mm will stop
the sound being transmitted along it.
This is not a problem of plastic pipe, it occurs in any boxed in guide,
which is one reason many wood shuts are 3 sided, with a number of cross
bars in the 4th side.

I do not work Wednesday Thursday or Friday.

Some years ago we fitted a drainpipe rope chute at a three bell tower
(Bolton-le-Sands) to provide a passage for the rope which didn't foul
the clock case, and it seemed to work fine - but it was a relatively
short run.
