arfur mo Posted January 7, 2008 Share Posted January 7, 2008 looking for door contacts to fit aluminium doors on domestic installneed to hide or make it as less obvious as possible can any one advise can you get the header trim off? if so (and the metal is aluminum) you can mount a standard surface contact behind it and the magnet in the trough at the top of the door. if not drill a 20mm hole either in to the header or frame upright with a stepped cone cutter and use the normal quick-fit contacts, both the above won't conform to G3 spec though so be careful. (i just thought i'd get that bit in before i got flamed ). regs alan If you think education is difficult, try being stupid!!!! Link to comment Share on other sites More sharing options...

Angus is right about G2, but then are these systems graded in the 1st place? my experience it would be rare requirement on builder multi-installs, all they usually want is a frilly selling point to stick in the brochure. the basic survival rule of any contractual site work is make damn sure any 'mistakes' were by permission or deed of another if you want to survive. so best you have a word with them to advise your professional concerns, then if they don't want graded and put it in writing your conscience is clear in both the liability and duty of care sense. regards drilling the door frames, in my experience only the Everest engineers have ever kicked up due to their triple insulation frames, but again get it in writing before you get your drill bits out. regs alan If you think education is difficult, try being stupid!!!!

luggsey Posted January 8, 2008 Share Posted January 8, 2008 looking for door contacts to fit aluminium doors on domestic installneed to hide or make it as less obvious as possible can any one advise We sometimes used to glue a cut bit of wood to the top of the door if it's the type with a channel on top with the magnet flushed into it. On the frame just fit a flush contact or if it's brushed/polished aluminium you can get a stainless flush contact. It won't be G3 though. ----------------------------------------------------------------------------------------------------------------------------------- Life is like a box of chocolates, some bugger always gets the nice ones!

What's the problem making it G2? ----------------------------------------------------------------------------------------------------------------------------------- Life is like a box of chocolates, some bugger always gets the nice ones!

amateurandy Posted January 8, 2008 Share Posted January 8, 2008 Yeah I have seen magnets stuck in on their own Going back to my infamous "new back door" thread (maybe best not to TBH) I ended up with a "naked" heavy duty magnet "glued" in the channel on top of the door (it was a tight fit anyway so wasn't going to move) and painted white to match. Did the job, but then it's a DIY install so not "graded". Link to comment Share on other sites More sharing options...
