Does anyone know how I can adjust these hinges on a PVC door

I hope the links work.

This one looks off center..

The hinge is deliberately made with an eccentric pin. By rotating
the plastic wheel (and hence the pin) using the screwdriver slot,
you can get some degree of adjustment. When you replace the
plastic cap, which should have a couple of pegs on the underside,
it stops the wheel from rotating in normal use.

Be careful to try and adjust them all evenly. It looks like one is
different to the others, so I'd reset all of them, then back out
again a notch at a time. This stops the door or frame moving as
much. I know they're not supposed to 'much', but UPVC doors do
experience thermal expansion and in our school I have to adjust
them every season, it seems.

One problem is they're usually delivered as a pre-set door/frameset
to a building site and some builders just whack them in any old
how, not caring if they're hung well or true, so it might be worth
making up a plumb line to check the verticals and a spirit level
for horizontals and make a decent job of it.

OTOH, a lot of the time it's suck it and see, a twiddle here, a
twiddle there and job's a good 'un .. .

My uPVC front door (which is the typical type with a frame with a
'sandwich' filler of part glass and part moulded plastic)
occasionally drops slightly and catches at the bottom. I have found
that this has nothing to do with the hinges - but is the frame itself
slipping out of shape (In effect the top and bottom of the door frame
start to slope down slightly). If I bend down and grip the underneath
of the door at the latch end and heave up, this puts the frame back
into shape and the door no longer catches. I perhaps have to do this
once or twice a year.

When I refer to the door 'frame' in this context - I am not talking
about the frame into which the door fits - but rather the outer frame
of the door itself, into which is fitted the moulded insert.

That's interesting, never come across this yet, but I can see how it
might happen .. and we may have a door with exactly this symptom where
everything's plumb and square but it still 'drops' and catches on the
bottom edge occasionally, however the hinges are set. I'll give it a
try next time, cheers.

You're welcome!
