Newbie here, sorry for dragging this topic up but I have the exact same problem as our friend here had. Although it is at my parents house, I went round there today and i am thinking it's a GU lockable drive mechanism with P14 handles like these
I am pretty sure the door will have to be removed, and then the mechanism unscrewed from the face of the door then slid out of the top ( or bottom)
I have manged to take some measurements of how far the locking points are and some door dimensions, I was wondering if someone would be good enough to point me in the direction of a replacement mechanism.
Basically on the frame of the sliding door there are 4 screwed in 'mushroom' type bolts that are static. there door slides into these bolts, you slide the handle down which operates the mechanism which locks the door shut then you use a regular key to lock the whole thing.
Between the centre of the lock to the centre of the tilt mechinism 100mm
Between each locking point 315mm
Door depth 30mm
Door width ( between side of the door where the locks are and glass payne 70mm)
I would like try to upload pics, ideally I would like to remove the door and remove the mechanism but my father is quite elderly and tbh isn't strong enough. My plan is to hopefully get the correct part and then get a few friends to give me a hand after work one night although this is proving difficult as they work shifts so i may get one saturday on this tops.
Any help would be greatly appreciated.
