Picture: http://ift.tt/2fT76Vz had some tubing with cabling that's not in use anymore and which I've already removed. Inner hole is 1.5cm (0.6") wide and the damaged plaster portion is around 4cm (1.6"). It's very deep, enough to reach the room on the other side.Thanks! via /r/DIY http://ift.tt/2gkL3HK
