Installation Instructions

TOOLS NEEDED

• Pen or Pencil to Mark Holes

• Drill

• Crescent Wrench

• Step Stool or Ladder

• Retaining Tool

Receiving and Handling

Upon receipt of your traffic door, uncrate and check unit for shipping damage and/or missing parts. Any damage to
the crate or packaging material should be noted on the carrier bill of lading. Exterior damage may indicate concealed
damage.

Doorway Preparation

The key to proper operation of your traffic door is that the lintel is level and the jambs plumb and square with the
lintel. Building materials, which make up the lintel and jambs must be in good condition and solid to accommodate
the weight and action of your traffic door.

Traffic Door Preparation

Check the dimensions of your doorway with those of your traffic door. The overall height of the traffic door panels
(including hinge frame) should be ¾” less than the height of your doorway opening. Tighten the lower threaded
adjustor (A) aligning the lower pivot pin (B) with the bottom edge of your PVC door panel (C). Open the spring arms
(D) and slide down over the spacer plate (not shown in drawing).

1. Secure the upper mounting plate (F) centerline of
lintel. If necessary, use shims to insure it is level
and square with the doorjambs. Secure with
proper fasteners (not supplied) depending on
your lintel material or weld in place.

2. Position lower mounting plate (G) aligning the
lower pivot hole (H) with the pivot hole (I) in the
upper mounting plate (F). Secure with proper
fasteners (not supplied) or weld in place.

3. Raise traffic door panel to the vertical position
guiding lower pivot pin (B) into pivot hole (H) in
lower mounting plate (G). Be careful not to
release the bearing enclosed.

4. Align upper pivot pin (J) with pivot hole (I) in
upper mounting plate (F). Screw out lower
threaded adjustor (A), which will raise the door
panel into its proper position. Be sure spring
arms (D) slide over the upper adjustor (E) located
on the upper mounting plate (F). A space of 3/8”
should be left between the horizontal hinge arm
and the lintel of the opening.

5. Tighten locking nut (K) to secure door panel in
place.

6. Use upper adjustor (E) to position the door panel
in the center of the lintel. After alignment is
achieved tighten locking nut.

7. Repeat same procedure for second traffic door
panel (bi-parting models only).

Adjusting the Tension

NOTE

The torsion spring mechanisms are adjusted at the factory
for normal operation of the traffic doors. Releasing the
tension completely is not advised and care should be taken
not to over-tighten as damage to the spring may occur.

To Increase Tension:

1. Open door panel to 90 degrees. Insert a
retaining tool (N) (not supplied) in the second free
hole of the adjusting ring (L) starting from the one
into which the pin is already inserted.

2. Allow the door panel to close slightly until the
retaining tool (N) inserted into the adjusting ring
(L) rests against the inside of the doorway.

3. Remove the pin and slowly recluse the door
panel until the inside hole of the mechanism
matches up with the new hole in the adjusting
ring.

4. Insert the pin (M) in the new hole.

To Decrease Tension:

The procedure is the same as increasing the tension
with the following two differences:

1. The retaining tool must be inserted only one

hole away from the pin.

2. When the pin has been removed, the door panel

must be opened instead of closed to insert the pin in
its new position.

NOTE

Supra Model door panels may be field modified. Ultra Model
door panels may be field modified up to 4” in width and 2” in
height.
