do you have the 89mm ( 3.5″) bottom plate to attach the chain ? Thank you

Hi Jean-Louis

Please see the link to our 89mm weights with the arms for chains to be applied to – https://www.blindsbypost.co.uk/blind-parts/89mm-white-vertical-blind-bottom-weights

The corresponding chain is here – https://www.blindsbypost.co.uk/blind-parts/vertical-blind-parts/bottom-chains/5-white-vertical-blind-chain-100-links

I hope that helps.

Thanks
Sophie
