Door Gearbox

[lexusdriver]

Hi Folks

Gearbox failed a few weeks back and latch wouldn't retract. Managed to take the gearbox out and a piece of metal had broken off inside, and was preventing latch movement. I managed to get it working for now, but want to preventatively repair.

Door is a Solidoor.

How do I size it up? I can't find any identifying marks on the gearbox. I can measure spindle distance, etc., but would appreciate a bit of a steer please.

Thank you!

First hit at toolstation after googling “replacement Upvc door gearbox” brought up what looks like an identical one.

Hope it was a lucky hit for you!

Thank you @vladcjelli!

I did see this, but struggling on the difference between 35mm and 45mm.

Being a store, I could just nip over to collect, and return if no good.

Thank you

If you can, take the failed one with, they’ll let you size it up at the counter.

Its the measurement from the centre of the lock barrel to the front edge, eg:
