Are your doors 2.1m or 2.4m and do you only have one or two per door? Do you think flush bolts are as strong/safe as the barrel ones or would you still rather stick with the barrel ones?

They are not very strong at all. They work for holding the door closed but you should not consider these as any form of security. If you do use them then I recommend one top and bottom. Paul Re: Double doors and flush and barrel bolts 3Jul 07, 2011 1:47 pm Thank you Paul. What length would you recommend for a 2.4m solid door? 150mm, 200, 300 or 400? Re: Double doors and flush and barrel bolts 4Jul 07, 2011 4:00 pm Hi, The longer the bolt, the more force that is applied to the top fixing point due to leverage. The main thing to consider is the number of fixing points, the type of fixing and the construction of the door itself. In my case the bolt that you linked to ended up splintering the bottom of the door because it needed a rebate to fit the bolt - so the timber is thinner, and it only has a single fixing point. My door broke just as a result of the timber swelling and normal bumps. I don't think it would have stood up to a serious attack - however this was in a 'safe' neighbourhood and the door itself had a large pane f glass, so if someone wanted to get it it would have been much easier to break the glass. Something like thishttp://www.lockweb.com.au/en/site/lockweb/Products/?groupId=488&productId=779 is probably more secure. It has more fixing points and is of more substantial construction. This is another option: http://www.gainsboroughhardware.com.au/hc_PatioBolts_Detail.aspx?PartNo=PB10BCK Paul Re: Double doors and flush and barrel bolts 5Feb 25, 2012 6:56 am When i put on double doors i only use flush bolts on the fixed door and use a standard door lock with a rebate kit on the opening door. I normally use a delf or equivalend heavy duty bolt which has multiple fixing points. I also always use a hardwood sill so that the bolt has something nice and firm to go into. If the doors were 2340h i would use an addtional flush bolt on the bottom of the opening door. If the door is veneered then you need to make sure the flush bolt is installed in the meat of the door, usually the first 28-32mm, i normally be my rebated doors made with an additional lock block top and bottom. Okay, then the choice is really about the build quality of the door itself which means the brand name.
