Each wooden fin is a 31' long, 14" wide and 2" thick. Glulam beams are more stable than milled lumber in these dimensions, greatly increasing the accuracy and longevity of the installation.

Along with a fine Louise Nevelson sculpture, the wall installation is visible to pedestrians walking to a nearby "L" station.
