The sleek new Hemisphere (?Hemi?) design is based on the original GrinderMinder and features a lower profile ?half-dome? top. Just like the original GrinderMinder, it looks great and secures well into edges of concrete or stone benches, walls and planters. The head of the Hemi GrinderMinder is 1_ diameter and 1/2_ high. It?s low profile is perfect for benches and seat walls. 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.
