MSR D-Flectors Bar End Mount Kit
Work great, hold tight!
Bought these to replace the expanding rubber type mounts for some bar-end mirrors. These things hold solid are easy to install. Note that they are the smaller diameter meant to fit inside of aluminum (7/8" or 1-1/8") bars, they do not work with standard steel 7/8" handlebars.
