Titanium disc with broad depression allows use with rounded feet as well as conventional cones. Great for heavy turntables, amplifiers and other components. Extra-thick dBNeutralizer pad provides grounding for vibration drainage. Works as a two-way decoupling barrier also, preventing vibrations from permeating into the audio rack or floor and subsequently reverberating back to the component or to other components, and vice-versa. For use on virtually any kind of shelf, platform, stand, bare or thinly carpeted floor. Fat Grounding Base does not mar or smudge. Suitable for components of virtually any weight. 1.57" wide by .375" tall (40mm x 9.5mm). Bottom of base to bottom of disc depression: .315" (8mm).
