This item is for ONE 3.5" (89mm) wide replacement slat (maximum length per slat 120"/3048mm). Please count the number of slats you need, then click to buy the correct amount. After making your payment please email us to let us know what length(s) you would like us to make the slats. Don't worry - if you should forget to tell us the length we will contact you by e-mail to cheque as we make all slats individually to order and do not have any "stock sizes". The best way to measure your existing slats is to take one down from your blind, lie it flat and carefully measure the overall fabric length. The fabric is 100% Rigid PVC fabric, weights and chains are not required for this type of slat. The photo is for illustration purposes only as colour/definition varies, please email us if you would like us to send samples of the fabric. PLEASE NOTE that as all slats are made individually to measure we cannot be held responsible for slats that do not fit due to incorrect measurements given (however we do always try to help put things right at minimal cost).
