Hi all, can anyone tell me what make model nightlatch you are using on alluminium doors, there are a few gibbons 2000 in this area and they dont make them anymore.

any n latch will fit or retro fit an alum door however the keeps are mostly electric latch.. yale 88 or 89 is a common one used i even saw one today on a security door used in conjuction with a panic bar system and an assa cylinder

As Stu says, any night latch set of the correct size can be used.

Sorry i've been away for a few days, your answers have confussed me. Now i may be being stupid but all the nightlatches I have in stock have a "lip" on them, on a timber door you cut a recess to accomodate this lip, but if i did the same on a hollow allum door there would be nothing to screw into. The ones I am being asked to replace are surface mounted.

@Tony: Thats what you would need to use on an ali door, surface mounted without a lip.

great, where can i get them?!! phoned duffels they had nothing same with the other companies i order from, as i say it was gibbons but they are now disconinued.

Any nightlatch set without a lip, and the correct backset - 40mm or 60mm will suit. As you say Gibbons only now make the latch with a lip and the lipless version for metal doors has been discontinued.

Ok i'm sure its me being unclear. Could you give me a name and model as suppliers seem unable too. Thanks

Check out the Union and Legge night latches

these are what i would  fit.
