What Does R1350 Mean?
R1350 is a restrained automotive convex curve with a 1350mm radius. It widens the rearward view with less visual distortion than more strongly curved glass and is slightly shallower than R1260.
Choosing the Correct Size
Measure the required diameter across the widest point of the original round mirror or housing. Select that exact diameter from the menu and confirm that 3mm thickness and R1350 curvature are suitable before ordering.
