Decide where you want to put your manhole. Check there is room between the studs for the panel. Measure up your panel then use your pencil to mark the centre point on the ceiling. Now measure out and mark the edges of the panel on your ceiling.
Check in the roof to make sure there are no electrical wires that you could accidently cut into. Use the keyhole saw to cut a small hole at the centre point. Now use the reciprocating saw to cut around the marked edges.
Insert your manhole frame into the hole. Make sure it is nice and snug. Then drill a pilot hole through the frame into the timber roof beams. Use screws to secure the frame in place. Finish off by inserting the cover panel.
Asbestos, lead-based paints and copper chromium arsenic (CCA) treated timber are health hazards you need to look out for when renovating older homes. These substances can easily be disturbed when renovating and exposure to them can cause a range of life-threatening diseases and conditions including cancer. For information on the dangers of asbestos, lead-based paint and CCA treated timber and tips for dealing with these materials contact your local council's Environmental Health Officer or visit our Health & Safety page.
When following our advice in our D.I.Y. videos, make sure you use all equipment, including PPE, safely by following the manufacturer’s instructions. Check that the equipment is suitable for the task and that PPE fits properly. If you are unsure, hire an expert to do the job or talk to a Bunnings Team Member.
