UNIVERSAL STANDOFF REGULATORS
The Universal Economy Standoff Regulator from Duro Dyne is a hand operated elevated regulator designed for use with 1/4” or 3/8” square
rod on externally insulated duct. The unique 10 degree foot allows the same regulator to be used on both square or round ductwork,
alleviating the need to stock multiple regulators. It is offered in four standoff heights: 1’’, 1-1/2’’, 2’’ & 3’’. The handle is locked in place with
a heavy duty high torque stamped wing nut and clearly shows damper position with embossed designations for open and closed. Reinforcing
gussets in four locations add to the rigidity of this regulator. An optional
UESO - UNIVERSAL ESO
score and Heto Notch allows the UESO to work for multiple damper fitting

DURO-TWIST™ REGULATORS
The Duro-Twist is a hand operated elevated regulator designed for use with square rod on both square and round externally insulated duct.
It is offered in four standoff heights: 1’’, 1-1/2’’, 2’’ & 3’’. The Duro-Twist is engineered with a strong friction resistance so it stays set
without any need to lock it in place. The high visibility yellow handle allows it to be easily found in the field on wrapped duct. The handle
position illustrates damper blade position on the outside of the ductwork.
Manual operation
(no tools)
The wing nut has a locking feature molded into
the nut. This secure locked fit eliminates any
movement from duct system vibration.

1/2” SHAFT LOC QUADRANT SETS (FOR DAMPERS UP TO 30”)
“Shaft Loc” Quadrants are stamped of heavy gauge steel and clearly indicate the position of the damper. The quadrant handle (available
for either 1/2” square or round shafts) is unique in that it locks the shaft of the damper to it by means of a powerful friction holding device
strong enough to cut into the damper shaft eliminating damper rattle. The shaft is easily locked with 1/2” open end wrench. Available for
square or round
ducts.

HAMMER ON DAMPER HARDWARE & ACCESSORIES
‘RAPIT’® DAMPER REGULATOR
Note: Not recommended for use
in systems over 300 o F.
The RAPIT is an inexpensive, rattle-free regulator for quick installation on balance
or splitter dampers. It is formed from rust-resistant, heavy gauge, galvanized
steel and installs in seconds. The Rapit will penetrate and secure to round
or rectangular damper blades up to 24 gauge steel. It has a fully retractable
bearing of zinc alloy, threaded to accept a 5/16-18 wing nut and a handle that
indicates the damper position. It’s as easy to use as 1-2-3.
1. Slip the bearing over the edge of the damper at the bearing line.
2. Lay the assembly on any firm surface and rap the prong with a hammer.
One blow drives the prong through the damper blade, holding it securely
to the damper.
3. When hit with a hammer, the prong will automatically form up tight by
the anvil, which is built into the bottom of the “Rapit” Bearing.

tools; just twist the extension fork over the threaded bearing and
slip the sleeve over the joint. Slide Rapit Extensions can also be
combined to accommodate liner thicker than 2’’.

MULTI-BLADE DAMPER HARDWARE
NEVA-BIND™ DURO BLADE KIT
FOR PARALLEL DAMPERS
Duro Dyne’s “NEVA-BIND” Linkage Bracket will always align itself to
assure smooth, non-binding operation even on the heaviest damper
blades. Above, or at unequal distance from the blade axis, it is
capable of adjusting itself all four ways, in-out, up-down, sideways
and rotation. Each carton contains all necessary hardware for one
blade of a parallel multi-blade damper.

OPAX® BLADE KIT
OPPOSED
FOR OPPOSED ACTION DAMPERS
Opposed Action Dampers minimize turbulence and the control of
the air is more linear. Neva-Bind, 4 way self-adjustability which
Duro Dyne “OPAX” kits feature, automatically compensates for any
construction inaccuracies as well as maintaining linear operation
and critical dimensions between linkage points. “OPAX” provides
opposed action of damper blades and holds the blades rigidly in
position eliminating rattle or flutter. These linkage kits contain all
the necessary hardware for two opposed action damper blades.

DAMPER ASSEMBLY UTILIZING SHOP MATERIALS
A. MAKING THE FRAME
(Same for both parallel and opposed dampers)
1. Cut a piece of channel for the frame 1/4” less
than the duct size, for clearance.
2. SIDE FRAME:
a. Mark off 5/16” from each end.
b. Divide the section inside these marks into as
many parts as there are blades required.
c. Mark for each pivot at the center of each
blade section (b).
d. Drill or punch a 5/8” hole at each pivot (c).
Insert self-oiling bushings (tap fit).
3. Weld the sides and bottoms of the frames. Be
sure to keep them square.
4. On large frames weld on corner braces to keep
the frame square. Place any braces on the side
of the frame which will not interfere with blade
movement. Attach top and bottom end stops, if
required. Cement felt, if required, with insulation
adhesive.

ACCESS DOORS
Duro Dyne Access Doors provide convenient access to the inside of ductwork for testing and cleaning purposes. All doors are manufactured
with an integral frame for minimal leakage. They are offered in a variety of sizes and styles for multiple applications including high pressure,
ductboard applications and more.
INSULATED ACCESS DOORS TAB STYLE
The IAD Door has been designed to create an airtight seal utilizing a moisture, oil and grease
resistant neoprene gasketing between the door to the frame and the frame to the duct. The door
panel is constructed out of 24 gauge galvanized steel and is filled with a 1” 1-1/2 lb. fiberglass
insulation (K factor .26+.03@75°F). The frame is 24 gauge galvanized steel with punched steel
tabs along each side, which locks the frame into the ductwork. Smaller frame corner tabs make
installation easy. Double camlock latches are used on doors 14” and larger. 12” and smaller have
one camlock. Special sizes can be fabricated with multiple walls of steel or see-through panels
or Cam-Lock only style.
Standard Sizes: Installation Note: All holes

onto ductboard. Simply cut the appropriate size hole in the duct, remove the release paper from the adhesive
strip on the door, and press the door into position. Complete the installation by pushing the nails provided through
the eight holes in the frame and capping them with the speed nuts, also provided, on the inside of the duct.

GASKETING
Wherever flanges are used in connecting parts of a duct system, the potential for air leakage exists. Besides contributing
to energy waste, leaks can also create noise. Sealing of ductwork can be accomplished with the use of gasket which
adheres to flanged surfaces. When this material is attached to a flange, which is then assembled to a second flange, the
material is compressed and fills gaps and irregularities creating a seal.
VINYL FOAM (PVC)
Vinyl Foam is a low density PVC Foam. When this material is attached to a
flange which is then assembled to a second flange, the material is compressed
and fills gaps and irregularities creating a seal.

DYN-O-TIES
™
Whenever your job calls for securing round flexible duct to outlets, pipes or fittings, you can do the job better, faster, and at a lower cost using
DYN-O-TIES™, flexible duct ties.
No tapes, no screws, no clamps. Position the flexible duct and slip a DYN-O-TIE around the flexible duct over the joint. Draw the DYN-O-TIE
tight with our ratchet action hand tool. A push with the thumb completes the job by clipping off the excess nylon tab for the neatest and
most secure connection you could want. Duro Dyne UV DYN-O-TIES are made to resist Ultraviolet rays and adverse weather conditions
when used in outdoor applications.
DYN-O-TIES, when properly installed, provide secure, self-extinguishing joints when connecting certain types of flexible duct listed by Underwriters
Laboratories Inc., class 1.

STAINLESS STEEL DYNA-CLAMPS
™
The Dyna-Clamp is an efficient way to secure flex or rigid round duct connections. The stainless steel band can withstand up to 60 PSI, as well
as extreme temperature conditions. The band is secured in place at the bridge by a slotted hex head screw. This zinc plated carbon steel screw
can be flipped up away from the band to offer a quick release when adjustments are needed. Dyna-Clamps are available in stock sizes ranging
from a 7’’ diameter to 20’’. Two or more clamps can also be connected together to accommodate duct diameters over 20’’.
