These blade arms are to be used with the Sinclair 44 in. brushed nickel ceiling fan. Before purchasing, please ensure you have identified your fan's model number and UPC to confirm compatibility. To identify the model/UPC number on your ceiling fan, please look for a label on the top of your motor housing (usually a silver sticker), which will include the manufacturer's model number and/or UPC number (12 digits). TIP: If it is difficult to see the label without taking down your fan, consider using your smart phone to take a picture of the label. If you can't find the label and you need assistance, please take a couple of pictures of the entire fan before contacting Customer Care so we can help you properly identify your fan. Material: Aluminum.
