This clear acrylic dome cover fits 20.5 inch (52cm) cotton candy machine bowls, matching most common countertop machines. Its fully transparent design lets you watch the sugar spin and check candy levels without lifting the lid, keeping things moving at a backyard party, school event, or candy stand. The sturdy dome shields the spinning bowl, containing sugar while blocking dust and insects, and keeps curious hands away from moving parts during operation. A bottom groove seats the dome securely against the bowl for a stable fit, and the seamless one-piece surface has no corners to trap sticky residue, so cleanup after each batch takes just a minute. At 21.1 x 21.1 x 13.4 inches and 2.34 pounds, it lifts on and off easily between uses, and its clear shape helps draw attention at events. Measure your bowl before ordering to confirm the right fit.
