Dropping off a 20-story building is all in a day’s work for Ray Graber, an employee of Jenkintown Window Washing.
In blistering heat Wednesday, he did it at least 10 times, down the south side of 1234 Market St., the home of SEPTA offices and the 13th Street station on the Market-Frankford subway line.
Graber adjusted his system of ropes and pulleys on the roof and carefully lowered himself onto a small platform seat. Swinging in a 10-foot arc hundreds of feet above the parking lot, he worked his way down the side of the building. When he reached the ground, he grabbed his seat, rode the elevator back to the top, and started again.
