Accessories and mounting brackets which clamp on to your rollcage or chassis tubing are great, but what do you do if your tubing isn't 1-3/4" diameter? These reducers are the answer! Now you can use a 1-3/4" bracket on 1-5/8", 1-1/2", or 1-1/4" diameter tubing. Works with any 1/4" thick clamp-on bracket. One reducer fits one clamp-on bracket.
