I intend to order 42 number replacement slats in total, for a bay window comprising one large window with 36 slats and two smaller windows each with 8 slats.How do order these on line to accommodate the correct chain sizes.

Hi Brian
If you place your order, just send us an email and we’ll send the weights and chains separately and not put them into the slats.
This way you’ll have a long length of chain.
I hope that helps
