Hemisphere (Hemi) GrinderMinders

          Cylinder GrinderMinder

Are you looking for a lower profile skateboard deterrent?  The Hemi GrinderMinder might be just the answer.  It is half of the profile of our original GrinderMinder, and it is installed straight into the surface, rather than at an angle.  The bottom of the Hemi is flush with the concrete or stone surface.  It is installed much the same as the original GrinderMinder – into a drilled hole (made with a 1/2″ masonry drill bit), the supplied plastic locking shim, and a dab of epoxy.  Very easy.  Very secure.
