1. Wall preparation – refer to following drawing
Note and understand the clear opening width and height dimensions of the
purchased door before proceeding with the installation.
The door must be securely mounted to a smooth surface. If necessary, based on
the wall construction, a metal plate would be installed to the wall as a mounting
surface for the T Brackets (by installer). Typically a 12” x 12” plate would be
needed.
The door, of course, needs to be mounted so that the head and roll are level and
square. The guide tracks must also be square and level in relation to the header,
the wall and each other.
Failure to properly secure, level and square the door components during
installation may result in premature wear and failure of components which will
not be covered by manufacturer warranty.

tracks should be 2 inches minimum to 3 inches maximum from the fully opened
curtain roll.
The Guide Tracks are slotted on one end. This is the top. The rear of the Guide
Track should be flat against the wall surface and are mounted to the wall using
Guide Track L Brackets at top and bottom of the track and using a two foot
spacing between. Tracks are mounted to the floor using two Guide Track L
Brackets if desired.
The slotted tabs on the top of the track are bent outward at an angle. Bend the rear
until it reaches the wall and bend the front to approximately the same angle. Insert
the end of the curtain into the track.

contacts the curtain when in the full closed position but does not press so hard to
deform the curtain. Install the Top Side Brush Seals, the seals are field fit. Mark holes

Splice Plate Roll Cover Bracket
If your Roll Cover comes in multiple pieces a Splice Plate is provided, as shown, to connect the
Roll Cover sections together. On wider Roll Covers, support brackets are provided as shown.
The Roll Cover Brackets should be mounted to the wall to support the weight of the Roll Cover.
They would be installed prior to installing the Roll as in section 3. They should be mounted so
that the Roll Cover will be level when installed. They should be mounted near each end of the
Roll Cover location and then spaced at approximately 24” apart. The Roll Cover is then lifted
onto the installed support brackets and secured to the wall as normal. The Roll Cover does not
attach to the support brackets, just to the wall. Any openings in the end caps, for shafts etc., are
to be done by the installer on site.
