Align the guide slots with the slots in the wall angles and fasten guides with the interior
windlock return towards the door jamb using the 5/16-18 x 5/8” truss head bolts,
washers, and flange nuts. Slide guides to set the “H” dimension as shown above at 1-
3/4” prior to tightening the guide fasteners.
Install the bottom bar stops with the same 5/16-18 x 5/8”
truss head bolts and flange nuts used to assemble the
guides (no washer). Leave the fasteners loose to allow the
bottom bar stops to pivot out of the way of the bottom bar
angle when the curtain will be pulled into the guides. You
will be instructed to tighten the bottom bar stop fasteners
in step #7.
STEP 4 INSTALL BRACKETS, DRIVE COMPONENTS, AND TENSIONERS
From the Dimension Tables on page 4, mark the width location of each bracket by using dimension A for the
operator side and 6” for the non-operator side. If the actual opening width varies from the packing slip width, adjust
these dimensions by adding or subtracting ½ of the difference to each dimension. Subtract if the opening is larger
and add if smaller. Mark the height location of the brackets by using dimension C. Verify the ceiling clearance
minimum from dimension B. Use a string and a level to verify that the brackets are level with each other. Adjust
bracket height as needed to level. Drill anchor holes and fasten the brackets with the anchors provided.
Brackets must be level to each other with respect to height.
Failure to level bracket heights will prevent door from
operating properly.
IMPORTANT!
If the door is to be chain hoist or motor operated, install the components shown below to the operator side of the
curtain at this time. Do not tighten set screws at this time, you will be instructed to tighten these in step #9.
