These universal weld-on triangular tabs give you a tough mount with the added comfort of a military-spec rubber grommet. The 1/4" thick steel will handle the weight of your oil tank or gas tank with ease, and the aluminum washer / spacer keeps the squish right where you need it. The supplied 5/16"-18 x 1" chrome button-head allen nestles right in and looks killer. If you want to compress the grommet even more simply file down the end of the spacer. These top-shelf universal tabs make quick work of making professional mounts for your motorcycle. These tabs are 2" high by 2-1/2" wide, from the flat to the bolt center is 1.4". Sold individually.
