DUO-FAST, originally called Fastener Corporation, was
founded in 1937 by the late Henry A. Torstenson. We were
doing business in a small plant on the north side of Chicago.

A rather crude compression tacker and hammer tacker, plus a
limited range of staples, represented the product line.

As a result of obtaining substantial government
contracts for the Duo-Fast staple tacker and
staples during World War II, the company grew
considerably, and hand held stapling was
accepted as an alternative to hammers and tacks.

Increased sales allowed us to expand with a
second manufacturing plant in Chicago in 1945.

It wasn't until 1947 that the company began
developing pneumatic stapling products. A major
automobile manufacturer had a production
bottleneck in their upholstery trim shop. They
attempted to adapt an air cylinder to a hand
stapler and found our squeeze tacker best suited
their job demands.

This, of course, led to the development of a
compact air tacker, which revolutionized the
stapling industry. Fastener Corporation's sales
slogan became, "Let Air Do The Job!"

Between 1949 and 1961, seven new Quonset
buildings were constructed to meet tool and
staple manufacturing requirements. Fastener
Corporation was now the acknowledged leader in
the fastening industry.

This was also a time that we started our
marketing leadership with tool development.

Even adding lumber yards as dealers.

In 1964, the first Duo-Fast nailer (CN-135) was
introduced.

A second nailer was introduced within three
years.

The new market opened by the nailers brought a
new period of phenomenal growth.

And an array of tools.
