Overhead Door Corporation offers a wide array of
rolling steel doors to meet the most demanding fire safety standards, unusual
opening sizes and discerning aesthetic requirements. Designed to close
automatically in the event of a fire or alarmed event, our fire-rated doors are
available for service door and counter applications in commercial, industrial,
institutional and retail uses.
All doors comply with NFPA-80, and are listed for both masonry and non-masonry
applications -- including installation to wood or steel jambs within drywall.
The Fire SentinelT time-relay release mechanism provides an added measure of
safety to control the doors' closure. Also available is the Fire MinutemanT
Chain Reset Hoist, designed to eliminate the need to release a fire door's
spring tension on fire drop mode and allows one person to reset the door from
the floor.

The 630 / 631 / 634 Series rolling steel, fire-rated service doors offer
superior protection wherever a listed fire door is required. Common
applications include factories, warehouses, mills, distribution centers and
parking garages. Customized fire doors are available for conveyor openings.
These doors feature fusible links mounted on both sides of the wall that
separate to automatically close the door. UL recommends a 165øF (74øC) fuse
link for ambient conditions for 100oF (38øC) or less, or a 212øF (100øC) fuse
link for ambient conditions over 100oF (38øC). Added protection features, such
as Fire SentinelT and FireLiter vision lites are optional.
Counter Fire Doors
The 640 and 641 Series doors are ideal
for openings requiring a counter-type fire-rated door. Common applications
include factories, schools, concessions, hospitals, cafeterias and retail
settings. Labeled with either a 3-hour Class A rating for masonry applications,
or a 1-1/2-hour Class B label in non-masonry fire walls, these doors are
designed to expand upward in a fire, allowing the guides to be installed flush
with the sill. Their compact, box-like form also provides an attractive
finished appearance that requires minimum sideroom. The 640 Series has exposed
components made of primed galvanized steel while the 641 Series exposed
components are of stainless steel.
Integral Frame & Sill Fire Counter Doors
The 660 / 661 / 662 Series integral frame
counter fire doors provide a handsome finished appearance for a variety of
applications, including food service counters. Available for opening sizes up
to 9' x 4' (2743mm x 1219mm), these doors carry a UL 1-1/2-hour Class B label
and are factory assembled as a complete unit with fully welded frames. The
frame comprises 16-gauge jambs and header, and is complemented by a 14-gauge
sill, plus hood and fascia. Added protection features, such as Fire SentinelT
are available as options.
