Permanent carpet sliders?

I’m replacing my BDI Avion audio cabinet with a Salamander Designs Chicago and want find a product that I can put on the bottom of the Salamander cabinet to allow me to slide the cabinet in/out as needed as it doesn’t come with rollers without it taking up any room.

Something unnoticeable and doesn't raise the cabinet off the floor to high. 

I know this thing will be heavy so I’d like to install them before any equipment gets put inside.

Ideas?
