The description for the CIPA Pontoon Boat Mirror # CM01877 is incorrect. There are more than 4 height positions. The 20" extension is measured from the bottom of the mirror to where the pole slides into the mounting bracket. When fully retracted this distance is 12.5". The extension can be set to any height between the retracted and extended measurements.
I have attached a review video below for your reference. You can see where the mirror is extended and retracted using the tension nut... view full answer...

The CIPA Sport II Side Mirror for PWC or Jet Boat part # CM11160 will provide around a 90 degree viewing angle which is about 45 degrees from the center of each side. Unfortunately, we do not have the tools to measure the radius of the convex plane on the mirror face. The manufacture was not able to provide me with this information either. view full answer...
I spoke with my contact at CIPA and found that the Rearview boat mirror, # CM11119, will fit on round or square tubes up to 7/8 inches thick so it will fit a 3/4 inch square tube. view full answer...
I went out to the warehouse and pulled a CIPA Custom Towing Mirror, Driver Side, # 10901, to measure how far the mirror portion is beyond the factory mirror on a 2010 Chevy Suburban. From the edge of the opening where the end of your factory mirror will be to the end of the glass it is 5 inches. To the center of the glass it is about 2-1/2 to 3 inches. So you will get at least that much more extension when using this towing mirror. The passenger side mirror is # 10902. view full answer...
