Door Hardware
Over the years, Von Duprin has
been an innovator in many new concepts to the industry.
These include the latch track threshold, drop forged
center case, concealed vertical rod device, reversible
exit device, narrow stile device, extruded aluminum
mullion and wood door concealed device, all designed
to meet the needs of architects and building owners.
The most innovative change took place in 1972, when
the company introduced the first pushpad exit device,
the series 33. One benefit of the new pushpad design
was its ability to be electrified. Shortly after
the 33 Series was introduced, the EL electric latch
retraction version exit device was developed. Within
the next few years, Von Duprin introduced the wide-stile
pushpad 99 Series, which has become the most popular
and versatile exit device on the market.
