The Grip Light was the first pendant light using the knurled finish. We wanted to utilize the knurling, usually used to optimize surface traction on machine parts for its soft fabric-like appearance.
The body of the pendant is thick-walled aluminum which is knurled and then anodized. The socket passes through an aluminum tubing which is knurled and then anodized.
The socket passes through an aluminum disc which is captured by a large internal spring clip. Assembled in this way it is exceedingly easy to change the bulb despite the inner diameter being too small for the average hand to fit inside.
All that is need to hold the lamp body and raise it up revealing the socket for easy bulb changes.
