The Avenue Popper Ledge is a fully granite flat-ledge with a mountable top section. One of the segments of the ledge can be popped out (hence the name) and propped up at an angle to create an up-ledge that can be used for grinds and manuals alike. Being made out of granite will give the ledge some weight so it won't shift around during use, and will also provide a realistic feel and sound for grinds.
