It comes with a base plate that you fit to the luggage rack. You can then remove the box with a simple (locking) lever, whenever you want, & carry it with the integral carrying handle. Shad make boxes in many sizes/styles/colours. The only problem is that when you buy the luggage rack/cissy bar that you need to fit it to, you'll have to remove the cissy bar, & make an adapter, to allow the box to hinge forward & open. Not a hard job if you're at all handy with tools. Here's a picture of the spacers I made out of 15 mm square hollow bar, to replace the cissy bar.[attachment=0:zrohqkek]b13.jpg[/attachment:zrohqkek]
