BETOOLL 16.5″ Wide Rear View Race Mirror Convex Mirror with 1.75″-2” Clamp for UTV Compatible with Yamaha,Polaris,Kawasaki MULE

Good description of the mirror and clamping dimensions, and supplied rubber spacers allow mounting flexibility up to 2” piping. All components appear to be either painted aluminum or plastic except for adjustment wing nut/stud which appears to be steel (magnetic). I purchased for install on a boat T-top structure pipe. It mounted well and size was what I was looking for. Used part of a supplied rubber spacer to provide the right clamping. I did replace the supplied steel wig nut/studs with stainless steel metric machine screws for the marine environment/corrosion robustness.
