Odyssey Mounting hardware is identical to the original Tiffany Studio hardware. Caps are unfinished, etched brass (6" wheel has a patina finish). Ring and wheels are machined brass castings that may need a little filing to clean off the rough edges.
Wheels are tapped 1/8" IPS (3/8" 9.5mm). This size thread allows the cap, ring and wheel assembly to be adapted to standard lamp bases.
