Re: Newbie about to run Cat5

["haweste" <haweste@xxxxxxx>]

Paul,

Thanks, I'm planning to just chase straight runs and go from the=20
sockets to the ceiling above, or floor below. Eventually I'll be able=20
to lift the floor in all rooms that I need to get too, it's just that=20
for now, some rooms are "off-limits" ! I will be leaving some
string=20
in the conduit - one of the tips I saw was to make the string twice=20
as long as the duct length then you could pull one cable one way, one=20
cable the other, or at least recover the string from the same end as=20
you started from.

TLC used to do the plasterers covers, have you seen them anywhere=20
else ?

Thanks again,

Tim.
