The OUTER CLAMP is a peripheral record weight that will effectively flatten warped records, pressing them against the platter to provide improved tracking by the cartridge as well as better damping of the record itself by bringing it into increased contact with the supporting surface. The addition of significant weight beyond the platter’s outer rim also delivers improved rotational stability. With an inner diameter of 316 mm the OUTER CLAMP is compatible with all Kuzma turntables and many others besides.
