If its cut between rafters the only thing required is around 2m of architrave to go around the cut. The Gyprock cutout should be able to be reused. Should cost anymore than a few hundred dollars Cutting Edge Kitchens and Cabinet Making http://cuttingedgekitchens.net.au http://www.facebook.com/pages/Cutting-Edge-Kitchens/290484196676 Mobile : 0419 430 575 PH: 9452 4772 Fax :9452 4772 cuttingedgekitchens@outlook.com Re: Adding a manhole 3Jun 02, 2016 8:55 am You can also buy pre-made manholes. https://www.bunnings.com.au/builders-ed ... t_p0730606 If you have standard spacing between trusses, it could just be a matter of cutting the hole and screwing something like this in. It's $30 plus half an hour's work. That quote probably includes quite a bit of contingency. There's the risk of problems in finding a suitable opening between the roof timbers. If there's a truss or joist running the length of the centre of the hallway, it may not even be possible to do it easily. There's the matter of going and buying the correct architrave, priming, painting etc., then if the hole coincides with a plasterboard join, you may not be able to re-use that sheet for the manhole cover, so that could mean finding, cutting, and painting a piece of gyprock, or getting some melamine for it. Re: Adding a manhole 5Jun 03, 2016 9:28 am I initially bought 600mm manhole frame kits at Bunnings but they did not fit as my ceiling battens are at 600mm centres and these kits were too large to fit between the battens. I exchanged these framing kits with 450mm framing kits but I then needed to fix additional timber noggins to support the edges of these smaller framing kits. This additional work meant that it was not a 5 minute job to install the manhole kits (at least for the first manhole). By the time I got around to the 3rd manhole it was less than a 30 minute job. The actual location of the manholes cannot be determined without access into the ceiling space to visually inspect the ceiling space as the location of the manhole needs to avoid bottom chord bracing, hanging beams and services such as cabling and air-conditioning ductwork. A clear space is required above and around the manhole if one intends using it to climb into the ceiling space. Re: Adding a manhole 6Jun 06, 2016 9:34 am That's handy to know. I noticed there's no spec on the minimum joist spacing on the webpage, but at least hoping it'd be set up for a common 600mm centres. Re: Adding a manhole 8Jul 04, 2016 6:27 am I'd be sure to frame around it in the ceiling with framing timber so it has some strength. When climbing into and out of a manhole you generally have to put some weight on the edge of the manhole as you step up/down. If it's just one of those kits from bunnings it makes it bloody difficult to actually climb into. Oh and use melamine panel for the manhole cover so that you don't get dirty fingerprints often they use painted fibro but it gets very dirty.
