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.
