Tux Saddle Bottle Cage Holder T 6202 Used as a fixing nut on the back side. Since there are only two genuine parts for one, it was necessary for four parts for two pieces. Since the home center had only zinc plating, I bought a stain here as I purchased a cap bolt. There are few who purchase similar products for purposes other than purpose of use. I appreciate Osaka soul / monotalou with many items.
