Just finished these up today. Thought I'd post some pics. I originally found a pic of these gates here at SMC, and through some diligent web searching, found the original designer, Mr. David Buchsbaum of Beacon Custom Woodwork (http://www.beaconcustomwoodwork.com/) . He was kind enough to help me a bit with my own gate project, since my ductwork didn't quite work with his original gate design. These gates are great. They work very well, and allow a high gate position near the main branch while allowing access within an easy reach. Got a higher ceiling? Just use a longer rope. There is a gasket on the side faces of the outer two members to allow free movement, but provide for a seal as well. I bought the gasket from a supplier to the CNC vacuum clamping industry.
