We call these our Elemental Metal double ferrule light sockets because you can get them in the classic elemental colors of silver, copper, gold and the most classic of all... black pearl? These double ferrule sockets work with almost all of our pendant light lampshades, including all of our super popular fiber string lampshades and handmade Italian ceramic pendant light shades.
So, why do we call them double ferrule? It's a fancy way of saying two rings. And that's exactly what these light bulb sockets have on them, two rings. The rings are there to hold pendant light shades in place. Most pendant light shade that have an opening between 1 - 5/8 inches to 2 - 5/16 inches wide should work with these double ferrule light bulb sockets.
The Elemental Metal collection of double ferrule light bulb sockets include your choice of cable strain relief clamp. The default option is a plastic conical strain relief. But we highly recommend the upgrade to the metal cylindrical strain relief. Make that small splurge and you'll love the result.
These are e26 base light bulb sockets. That means that they are "standard" base sockets and any light bulb with a normal size base will work with these sockets.
These light bulb sockets work great with our pendant light cloth covered wire fabric cords.
