Thanks for the help everyone, the client came back with 'finger support'

Vingeropleg -Steel tribar, slat flooring This is a type of slat flooring grate for pig housing. It is made of welded rolled-steel bars (usually triangular) and is lighter than the more common cast iron slatted floor sections. It is often used for farrowing sows while cast iron grates are used for piglets (warmer). You can see an example here https://growket.com/en/pig-floor-system/

or ...maybe some kind of finger operated latch/edge or something, to open them with?

oops, only just read phil's:

If so, could the "vingeropleg" be something you put your fingers underneath to lift it?

There's a picture of a grid with a 150-cm vingeropleg here (picture 2), but I'm none the wiser. http://www.agrisell.eu/advertentie-20200224080630.aspx
The ad is only a few days old - why not email the advertiser and ask?

Michael Beijer Feb 27, 2020:

hmm I wonder if it's some kind of ‘finger guard’?

Richard Purdom (asker) Feb 27, 2020:

yup, they call them 'slats' in fact. For livestock, allows manure to drop through. In the context of the sentence nothing makes much sense though!

I've been researching rooster/grate, but I'm still not sure what it means. Is it flooring? If so, could the "vingeropleg" be something you put your fingers underneath to lift it?
