Root beer float? Subtract the root beer and you've got Connected-Fidelity's Float, a ball-bearing isolation footer with top pimples or an add-on plate with M6/M8 bolt. The standard weight rating with POM spheres in chromium-steel races is 30kg. For heavier loads, the ball bearings turn chromium steel to not deform. A set of 3 or 4 standard Floats is £346/399. Additional speaker plates add £199.
