If you dont angle it, you move the entire unit and the drawer stays open/closed, unless mounted to the wall, then nothing happens. This extension worked perfectly. Don?t even fit waaaaay to small. PERO PEQUEÑO Y CONFUSO AL ELEGIR LAS TALLAS YO USO 31 MX Y 13 US PERO EN ESTE PRODUCTO SI ES NECESARIO PEDIR EL 14 Da hätte ich ein strapazierfähigeres Material erwartet. I can honestly say I can wear them all day and well, they are just comfortable. (Side note: Despite the marketing blurb about "we do things different here in the South, etc. For my ears they are super comfortable and have great bass. Fits perfect, very comfortable. Best boots Ive ever owned.
