Anyone find they are too short, i just had a job there, i fixed the original problem, but even when i had adjusted the doors to the max, to get them as close together as poss the door would still not latch, i can only presume the doors were made too narrow, is this common? anybody came across this?

It sounds like the keep needs adjusting especially if you have made other adjustments to the doors.

I was repairing the doors, there was no adjustment on the keep to move it towards the latch, even after removing all 6 hinge covers and giving the max adjustment, the latch did not reach the keep, they are on a conservetory and have never engaged, in the end i had to take the keep off pack shims behind it and refix.

Seems strange that the other parts were engaging, but not the latch ! Was the latch fully extended (ie was it coming all the way out) ? My only concern with "padding" the keep out would be the strength of the repair.

Overall it sounds like a c**p installation, and the customer should have had it fixed while under guarantee.

There are many reasons for this to happen.............

Frame made to wide

Door sashes made to small

Doors hung wrong in the factory

Badly glazed doors

Dummy mullion not correctly fitted, behind the dummy mullion are spacers or packers ( not always ) and you can fit thicker packers behind the mullion depending on the system

French doors not fitted correctly, this is the main fault with theses doors, the fitters generally fix the hinge sides to much and cause the sides of the frames to go further into the wall moving the centre locking systems away from each other

To repair this.......

Adjust hinges ( if they are adjustable )

Remove dummy mullion, fit packers and refit mullion

Remove fixing screws from frame sides, pack out frame and fix screws

Replace centre stricker with a thicker version

Remove glazing beads, move sides of door sash away from glass and pack the gap with glass packers, refit beads ( silicone packers as they drop down after a while )

Last pack centre strickers

Probably just badly fitted doors. I had this on a pair of UPVC doors the other day and had to adjust the doors to their max to get the latch to enter the keep. Apparently they'd never been right.

re badly fitting doors

Postby haldor » 23 Jan 2006 2:54

Have found this problem many times too. Always on poorer quality conservatories or porches. I think it's because of the general instability of the structure being made from upvc. The whole structure moves in time causing an overlarge gap between door and frame. Had to pad the keeps out to engage bolt.

I have once or twice ome across badly fitted IMO doors and have managed to overcome latches that dont engage fully. I have never attempted to adjust doors at the hinge side, mainly because I do not know how and simply dont know how or what to adjust. I dont want to start unscrewing screws and bolts without knowing their function. Anyone got any pics/info/links on hinges and their adjusting points please?

regards

The hinges adjust usually with an grub screw, most doors have to be open.
Open the door and on the inside of the hinge top and bottom there is a small allen grub screw as you turn these you will see the door move in or out. This works on a cam so as you turn the grub screw it pushes the can in or out but there isn't alot of adjustment on these.

thanks - i have noticed these allen screws and assumed that their function was to adjust the door. But it is nice to have it confirmed by someone who knows. There doesn't seem to be alot of adjustment available though!

On older doors there are small grub screws these just hold the hinge pin in and they adjust from the top same principle still works on a cam.
the newer ones have the adjusters on the inside of the hinge so you have to have the door open and they are not always allen key they can be a poz drive head.

Hi this is my first reply so here goes.
UPVC doors are just like boxes when you take out the stuff in the box the box is not strong at all, fill it back up then the strength returns. If after trying to straighten up the doors this still doesnt work. Get yourself a San Carlos knife and deglaze the top beading. Then jack up the bottom of the door with a flat boor as much as you can, this will create a gap at the top of the door between the glass or panel and the top. Get some packers and pack this out as much as you can. Release the tention on the metal flat bar, then try the door. This is a quick way of getting over droopy doors.
