Install 4 Skate "wheels" to the top of your Soundboks 3/4 in just a few minutes. Presto! You can now stack another Soundboks 3/4 on top, super stable. To install, just unscrew the top rubber ball screw and, in its place, install a Skate wheel using the provided screw. Repeat on the other 3 top ball corners. Keep the original screws so you can return your Soundboks to "stock" at any time you wish.
