If you’ve had or have a polaris or can am with accessories that use the quick attach systems the manufacture poorly designed, you can use them on your CFMOTO, the Polaris for example, sportsman’s run a 1” hole in the rack for attachments (see pics), not every box will fit though as there where year layout changes, the ranger/general and I believe rzr used a 1.5” hole which may not be compatible with YOUR VEHICLE so measure and see what you have.
My 19 800XC had the 1” holes in it already, I didn’t want to drill or cut into my beautiful new plastic racks so I utilized what was there, it’s not quite as stable/solid as a universal 4 bolt pattern but it works for light and medium duty thing. Don’t expect your box to survive massive jumps to flat ground but for trail use or yard work it’s fine. The accessories for lock and ride and Linq are more expensive overall but it can be convenient.
On my 800 I’ve got Kolpin dual grips PN:21516 for Polaris sportsman. With a little tweaking it can be made more sturdy but if there tight enough not to flop around then you should be set, use your finger on the metal base on the bottom to help stop rotation and get it tighter.
