Our newest record clamp makes several key improvements over the previous generation of clamps. First, the adjustable knob and upper half of the clamp is machined from solid stainless steel. By using solid stainless steel, the clamp adds even more mass and mechanical damping to the table. Since the stainless steel knob is more dense this translates to even better warp reduction when playing records. Also, the coupling mechanism is now also machined from stainless steel instead of Delrin to facilitate much more secure and precise coupling to the record and spindle.
