| Note
:Drilling the operator holes is one of the most important steps to a
successful installation. Make sure that the strap or dive rod can operate
the shutter freely without touching the wall or protection tube.
Otherwise, noise and more unwanted friction will occur and make the
shutter harder to operate, or possibly inoperable.
If the operator hole passes through a hollow wall section with loose
insulation, place optional PVC protection tube through the hole. This is
also recommended on block walls where hollow sections are possible. Caulk
the inside and outside wall around the tube. With the strap-operated
shutter, the straps should be fed through the operator hole before setting
the box into the tracks.
As mentioned earlier, field conditions vary and this can change the
procedure. For some installation, installers will secure the strap inside
the box, install the box and then feed the strap through the operator
hole.
Note : Before drilling through
any wall, avoid any drapes, valances, cabinets and any other interior
obstructions.
