1.Fitting of the Mounting Plate and Positioning of the wall Hole
When the mounting plate is first fixed
1.Carry out, based on the neighboring pillars or lintels, a proper leveling for the plate to be
fixed against the wall, then temporarily fasten the plate with one steel nail.
2. Make sure once more the proper level of the plate, by hanging a thread with a weight from
the central top of the plate, then fasten securely the plate with the attachment steel nail.
3. Find the wall hole location A using a measuring tape
