Nylon Washer - Marshall jack

Use this washer on the old style Marshall Jacks if your face panel is less than .125" thick

The chrome nut only tightens down so far leaving a .125" gap
The old style jacks come with a thin red fiber washer and so you will need one of these black nylon washers also.

These washers are approx .065" thick
Hole is .44" and Outer diameter is .75"
