*Size 30 does not include collars.
* Remove the basic type mounting screws and use the mounting screws included in the foot
bracket to secure the foot bracket to the cover. Use the collar as a spacer for the cover
counterbore part and secure it together with the foot.
* For size 30, be careful not to drop the cover when removing the basic type mounting screws.
Additionally, do not mount the foot bracket with the pressure applied to the port.
