This special mounting clamp makes it easy to mount a RaceMirrors Racing Mirror to a tube-frame car. The 1/4-28 threaded stud fits Race Mirrors made after 2016*, and the aluminum clamp fits over 1 1/2" OD rollcage tubing. Sold individually, one required per mirror.
* Prior to 2016, Race Mirrors Club Series mirrors had a 10-32 threaded stem. The CIS GT Series has always had 1/4-28 threaded stems.
You can backdate this clamp to fit older Race Mirrors or SPA brand racing mirrors by changing to the Stainless 10-32 Ball Stud, Part No. 5168-305 (sold separately).
