UPVC Door lock mechanism points keep coming out

Post by fixit9660 » Wed Jun 28, 2017 2:50 pm

I've got a UPVC door with a 5 point multipoint locking system with a "GU" logo and the numbers "6-22922" on the top and bottom lock mechanisms.
The door/mechanism locks fine. My problem is that after opening the door, if I release the handle, all the 5 locking points just slide out of
the door into the locked position, meaning I can't close the door without pulling the handle into the down position beforehand. I'm guessing
there's something broken in the centre handle/gearbox assembly but if someone could point out what to look for it would be a great help.

sounds like a spring/latch has had it in the gearbox

you need to find out what size backset you have.

Oh the Backset is 35mm, and the handle-to-lock is 92mm. I'm gong to take it apart shortly to confirm identity of the gearbox.

Hi flash.
Thanks for the prompt and helpful response again, much appreciated! :thumbleft:

I definitely have the old GU gearbox type; it's identical to the one shown at https://www.handlesandhinges.co.uk/mult ... nufacturer[]=GU on the left. (Mine also has "35/92 E-19786" stamped on it.)

I'm a bit confused though. You said plenty on ebay - avoid the cheaper copies, which is fair enough, but how much do I have to spend to do this please? Do you have a recommendation please?

Thanks,

Andy
