Pro-Ject Cork & Rubber-it 3mm Thick Turntable Mat

Three Millimeters of Cork and Rubber, for a Thin Metal Platter

The Pro-Ject Cork & Rubber-it is sold each, one mat per turntable. This is the 3 millimeter version, and Pro-Ject is specific about where it belongs: on a thin metal platter, which needs more damping than it can provide for itself.

A thin metal platter rings. It is stiff, it is light, and there is not enough material in it to absorb what the stylus puts in. Three millimeters of a cork-rubber blend gives that energy somewhere to go before it reaches the record.

A Blend, and Enough of It to Matter

Fit, Load and Materials

The mat is a blended mix of cork and rubber rather than layers of each. Rubber supplies the acoustic control and cork supplies the anti-static behavior, because neither material manages both alone. It adds under 0.5 pounds to the platter.

Three millimeters is enough thickness to change how high the record sits. On a tonearm with height adjustment that is a five-minute correction; on one without, it is worth measuring the mat you are replacing before you order.

Pro-Ject's guidance settles which of the two you want: the 3 millimeter mat on thin metal platters, and the 1 millimeter version on a platter dense or heavy enough to be doing the damping already.

Who Is the 3 mm Cork & Rubber-it Best For?

• Your platter is thin metal — this is the thickness Pro-Ject specifies for exactly that case
• Your platter rings when you tap it — three millimeters of cork and rubber is enough material to stop it
• Your records attract dust — the cork in the blend keeps down the static charge a felt mat builds
• You are replacing a thick felt mat — the height change is small, so tracking angle stays close to where it was
• Your platter is dense or heavy — Pro-Ject specifies the 1 millimeter version for that, since the platter is already damping itself

How Do You Fit It?

Take the old mat off the platter. Lay the new one down, line the hole up with the spindle and smooth it flat so nothing is trapped underneath. Three millimeters will move the record enough to notice, so reset vertical tracking angle if your tonearm adjusts for height.

Pairs Well With

What most turntable mat owners shop next.

• Record clamps and weights — a mat only damps what is pressed against it
• Record brushes — a dry sweep before every side
• Stylus force gauges — a new mat changes arm height, so it is worth re-checking
• Cartridge alignment tools — the setup job that decides how a record tracks

Frequently Asked Questions

How many do I need?

One. The mat is sold each and a turntable takes a single mat.

Should I have the 3 mm or the 1 mm?

Pro-Ject's rule: the 3 millimeter mat on thin metal platters, the 1 millimeter on dense or heavy ones. A thin platter needs the damping; a heavy platter is already providing it.

Why cork and rubber together?

Rubber gives the acoustic control and cork keeps the static down. Pure rubber overdamps and traps charge on the record; felt holds static and does little for a metal platter.

Will it change my tonearm setup?

Three millimeters is enough to matter. Measure the mat you are replacing, and reset vertical tracking angle afterwards if your tonearm has height adjustment.
