Vintage Whitting and Davis Stainless Steel Shark Mesh aka Ring mesh aka Architectural Mesh.

This Panel is from 1998 or so. It was part of a chandelier drape for a built in light fixture. The panels were uncut for the piece so this is a single full panel.

The Panel is approx 13" x 24"

These panels are made up of stainless rings.  Each ring is 1/4" diameter 

I believe this is the Large size #9 Whiting and Davis Ring Mesh

Base metal — Stainless Steel

Wire diameter — .031œ / .79mm
Outside ring diameter — .275œ / 7mm

The panel weighs approx 14-15 oz
