Pro-Ject Cork it Cork Platter Mat

A Cork Mat, Because Felt Holds Static and Rubber Overdamps

The Pro-Ject Cork it is sold each, one mat per turntable. It is a plain cork platter mat, made to replace the felt one that came with the deck. Cork sits between the two materials most turntables ship with, and that is the whole argument for it.

Felt is smooth and cheap, but it holds a static charge that pulls dust onto the record, and it damps a metal platter poorly. A thick rubber mat goes the other way: it overdamps, and it isolates the record enough that the static stays put and comes back as clicks.

Cork, Between Felt and Rubber

Fit, Load and Materials

The mat is cork throughout. It makes firm contact with the platter, so charge drains away rather than building on the record, and it damps a metal platter far more effectively than felt manages. It adds under 0.5 pounds to the platter.

It is a flat disc that drops onto the platter in place of the existing mat, with nothing to fit and nothing to glue. Cork also grips a record more firmly than felt, so a disc stays where you put it.

Changing mat material changes mat thickness, and mat thickness sets how high the tonearm sits above the record. Measure your existing mat before ordering, and expect to re-check vertical tracking angle once the new one is down.

Who Is the Cork it Best For?

• Your turntable has a metal platter — cork damps metal far better than the felt mat that usually ships with it
• Your records attract dust — cork does not build the static charge that felt does
• You find rubber mats dull — cork damps without the overdamping a thick rubber mat brings
• You want a mat you can simply drop on — no fitting, no adhesive, and the old mat lifts straight out
• Your tonearm has no height adjustment — a mat of a different thickness moves the record and changes tracking angle with no way to correct it; match your old mat's thickness from turntable mats

How Do You Fit It?

Lift the old mat off the platter. Drop the cork mat on, line the hole up with the spindle and press it flat so there is no air trapped underneath. Play a record and listen for the arm sitting level. If the deck has arm-height adjustment, reset vertical tracking angle now.

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.

Will it fit my turntable?

It is a standard platter-sized disc, so it suits most turntables. Check the diameter of your platter and the mat you are replacing before ordering.

Why cork rather than felt or rubber?

Felt holds static and damps a metal platter poorly. Thick rubber overdamps and traps the charge on the record. Cork makes solid contact, drains the charge and damps the platter without deadening it.

Will it change my tonearm setup?

It can. Any change in mat thickness raises or lowers the record and alters vertical tracking angle. Measure the old mat, and reset arm height afterwards if your tonearm allows it.
