Hi there, I am no longer in need of this wonderful Stainless Steel Center Weight that was custom made for me. The spindle hole will fit most spindle as it fits on my VPI Platter beautifully.
Seen here on my VPI Platter:


Specs are as follows:
Top diameter is 2.5 "
Bottom diameter is 3.5"
Height is 2" tall
I would say it that it is between 1.5 - 2 lbs.
