This fan blade fit an old Sears model 452.802610 12 inch oscillating fan. However, the blade has a smaller diameter than the original fan blade. The 12 inch version of this blade is only about 11 inches in diameter. (Note that the product description states that the radius of the "12 inch" blade is 5.6 inches.)The shaft nut included with the product is for an approximately 7 mm diameter shaft, which is larger than the shaft of the Sears fan. The end of the shaft on the motor of the Sears fan is reverse threaded. I can't tell if the nut included with the product is for reverse threading. The old shaft nut from the Sears fan worked to secure the new blade.The new blade arrived packed only in a plastic envelope. One of the blades was bent out of shape. Technically, that's an aspect of the seller, not of the product itself, but it's worth keeping in mind.So great I could find a replacement blade for my pedestal fan that was less than a year old. I saved money buying this replacement blade instead of having to buy an Entirely new pedestal fan .I would recommend.
