6.
Mark the location of the second bracket along the same horizontal line. The two top
brackets should be spaced a distance of about one-half the width of the frame
assembly. This horizontal distance is not as critical as the vertical distances. Verify
that the marked holes are level.
7.
Use a carpenter's level to mark a lower horizontal line for the location of the lower
mounting brackets. Note that this line should be spaced at a distance equal to the
distance measured in step 1 above, minus 32mm.
8.
Verify that the marked holes are level and at the exact distance apart as calculated
in the previous step. Once verified, drill pilot holes into the wall. If you will mount
the brackets to wall studs, drill 4mm pilot holes. If you will be mounting to a
concrete wall, drill 5mm holes for the anchors.
9.
Use the ø5x18 screws and anchors (if applicable) to secure the brackets to the wall.
10.
Use a #2 Phillips screwdriver to "unlock" the two lower brackets, while keeping the
upper brackets "locked".
11.
Using two people, lift the frame and hang the upper edge on the two upper
brackets. Ensure that the bottom of the frame is in the locking edge of the lower
brackets, then use a #2 Phillips screwdriver to "lock" the two lower brackets to
secure the assembled projection screen in place.
