How a Squeegee Handle Became a Life-Saving Tool on September 11, 2001

Window washer Jan Demczur used his squeegee to pry open the elevator doors where he and five others were trapped. Taking turns, they used the squeegee and its metal handle to hack through drywall so that they could squeeze through and escape down the stairs. (National Museum of American History)

How a Squeegee Handle Became a Life-Saving Tool on September 11, 2001 - On September 11, 2001, window washer Jan Demczur was ascending One World Trade Center in the elevator with five other men. When the car came to a sudden halt and then started plunging downward, someone in the cab managed to press the emergency stop button. The elevator cab mercifully stopped, but the men smelled smoke and knew they had to find a way out.

The events of what happened next, as told to Smithsonian magazine writer Victoria Dawson for her July 2002 article “Handed Down to History,” include a harrowing escape from the elevator after the men pried open the doors, only to be faced with a wall of Sheetrock. Fortunately, someone had a pocketknife and the men began cutting their way out. But to break through the three-quarter inch thick layers, Demczur recalled, “was going to be hard.” Still, the men persevered.

‘We just started working. Focused on this way to get out. We knew we had only one chance.’

And then, that one chance—that blade—slipped out of Demczur’s hands, falling right down the elevator shaft. “I was very upset with myself. We had a problem and now a bigger problem.” A man standing next to Demczur reached into the window washer’s bucket and seized the Squeegee handle. One more chance.

Squeegee handle underside: A coating of white drywall debris is still visible on the underside of the squeegee handle Jan Demczur used to dig a hole through a wall in his escape from the World Trade Center.
They returned to the wall, systematically cutting furrows, both vertical and horizontal, creating at last a sizable depression in the first two layers of Sheetrock—some 18 by 20 inches in size. ‘We didn’t know what was going on [in the building], but we knew time was running out,” Demczur said. They kicked and kicked again, breaking through the triple layer of Sheetrock only to find. . .still more Sheetrock. Mercifully, it was a single layer, three-quarters of an inch thick. Easily punched through. Finally, they pushed against a tile wall and found themselves underneath a sink in a men’s room.

The six men escaped the building. It took them 90 minutes from the moment the elevator cab had halted in the shaft, but they reached safety only minutes before the tower collapsed—the second tower to do so. The tool that saved their lives, the Squeegee handle, joined the collections of the National Museum of American History in 2002 when Congress designated the museum as the official repository for materials honoring the victims of the September 11 attacks, when 2,996 were killed at the World Trade Center in New York City, the Pentagon in Virginia and aboard Flight 93 when it crashed in a field outside Shanksville, Pennsylvania.

This week, the museum announced that the Squeegee handle along with 26 other artifacts from the museum’s collections are on view at the National September 11 Memorial and Museum. Director John Gray noted that the 14 items from the World Trade Center, the eight from the Pentagon and the five from Shanksville, Pennsylvania, "tell the story in ways that words cannot."

Pimping the Unger 0° Swivel Lock Handle



Mark Strange from Toronto, Canada & of "Beautiful View"has come up with the solution for interchanging your Unger 0° channel to make it a quick release. Mark adds,"many folks who have tried the Unger 0° swivel handle love the versatility of it but the most common complaint comes from having to loosen the two nuts and bolts to change out the channels/rubber." "If you have an Ettore Super System handle lying around, you can remove the quick-release mechanism from it and use it on the Unger." "The screw holes are the same distance apart. You will still be using the Unger plate as this will keep it a clipless system." "Remember to use the springs in between the nuts and the holding plate." He adds, "I had to drill out the screw holes a bit on the Unger because the Ettore screws were too tight; you need play."
Above you can see the Unger swivel-lock 0° handle & below with the modified handle interchanged with the Ettore Super System locking system.
See here on how to utilise the system for fanning with a pole. And see here on modifying your Ettore Contour-Pro handle.
