The Blendtec FourSide Jar is a 75 oz replacement or spare jar for Blendtec blenders, sold with a red hard lid. It has a 3-inch wingtip blade and measurement markings in ounces, milliliters and cups up to 32 oz. The jar is made of BPA-free Eastman Tritan copolyester. It is built to sit inside a sound enclosure, so it suits commercial kitchens and Blendtec owners who want a second jar for back-to-back batches. Against Blendtec's WildSide jar, the FourSide has a squarer shape and a smaller blade, which many owners find better for smaller, thicker batches and for dry or fibrous ingredients.
