Visitors Step Out Onto Chicago's New Ledge
July 6, 2009

The Ledge, a series of glass bays that extend from Chicago's Sears Tower's 103rd floor, opened to visitors last week. The Ledge reaches out more than 4 feet from Skydeck Chicago's west side, giving visitors unobstructed views of the city — 1,353 feet straight down. Chicago-based MTH Industries served as the contract glazier. Each glass box is comprised of three layers of glass laminated into one seamless unit. The low-iron, clear glass is fully tempered and heat-soaked for durability. The glass panels weigh 1,500 pounds.
