A great way to display your game or movie cases on your wall . This part can fit 9 cases . The width of each slot is 16mm if its too loose you can add some thin felt pads to make it snug . This is one of many parts from this design , please make sure you choose the right ones . This exact model is the middle without sides of extendable design and has alignment holes on both sides (Connector pins are not included , check my profile )
