Am about to move house / office ( from Getagun to KZN - Toti ) and am considering installing eco-tubing ( I think that's what it is called - square plastic tubing with clip on front face ) at ceiling height for my alarm cables, network cables, TV arial cables, etc. Should I be able to put all these cables in the same tubing, or would there be some form of interference between them ?

Can anyone point me to where I can find what sizes of tubing are available ? -- our local hardware only stock 1 size, but I am sure there must be a whole range available - pref. looking for a supplier in the Toti area.

Also, am looking for an alarm system installation person that can supply / install the sensors, control panel, etc.

Any pointers greatly appreciated.
