New blind stopper blade holder. This part installs from the inside of the bowl and prevents the blade assembly from jumping out of place. Both o-rings are included.
Note: This blind stopper is recommended to be used in conjunction with a blade holder insert. Using both the blind stopper and the blade holder provides the best protection from blade hop. You can find the combo set here.
Important: The blind stopper should never touch the attachments and is not designed to solely keep the blade down during mixing operations. If you are experiencing damage to the blind stopper there are other issues that must be address first.
The first step is to use the combo set, which uses the blade insert. This insert locks the attachment in place and prevent the blade from "unlocking" and interfering with the blind stopper.
The second step is to address damage to the attachment shaft. The shaft uses two interlocking fingers that lock the blade into place with centrifugal force. If those fingers become worn or damaged, the blade will not lock in place and will be forced upwards during the mixing cycle. This can be fixed by using our rotor exchange program.
If you have any questions or concerns you can give us a call at: 800-651-9271.
Note: Before ordering be sure to check the lid insert! if the lid insert is removed or worn, the blind stopper will not fit tight. (See image above) If that insert is missing select “plastic lid insert” option above.
