The vented Gripper™ lid seals liquids in the jar during blending. But it does more than that—the removable vent allows steam to escape while blending soup or hot liquids. And an additional opening means you can add ingredients without even removing the lid. The vented Gripper™ lid fits all WildSide+, FourSide, Rebel, and XR jars; regardless of which blender model you own. *If you're looking for more blender accessories, then check out our available stock .
