3. Choose if you want a fixed angle or a rotatable angle. 

A) Fixed angle - No need to use the big washer.

This clamp has an 18-tooth locking system providing 18 locked-in viewing angles. 
You might need a couple of test rides to find the best viewing angle.

B) Rotatable angle - Place the big washer on top of the clamp.
