Unfortunately, you are unable to upgrade the backboards to larger sizes. The steel for each goal that extends from the pole, attaches to each backboard differently.
Are the CV (clear view) backboards as sturdy as the goals with the “reinforced” glass, such as the GSI, GSII, and GSIII?
The reinforcements on the CV models are redesigned to go to the side of the glass, which gives it similar stability to the GS models, and allows it to have the clear view backboard.
Both the Medium Weight and Heavy Weight rim have one spring. The spring is stronger in the Heavy Weight rim and the overall “box” size of the rim is larger – thus the different mounting patterns.
For high school, college, and professional basketball, the regulation height is 10 feet to the top side of the basketball rim.
Gauge refers to the thickness of steel. The lower the gauge number correlates to thicker steel. Example: 7 gauge is thicker than 11 gauge.
