I believe the shelving brackets are made by Doug Mockett & Co., Manhattan Beach, CA. I've seen something similar to these in his catalog....

I checked the site -- No Luck! suggestion welcome.

The brackets were purchased from a catalog. I believe it was Crate and Barrel or West Elm. The brackets were modified in the field, clipped at the end. The wood shelving was sourced locally and modified in the field, planing the edges. Thank you for asking.
