4.3 Flat Tile
Roof Anchors fixed to Rafters
1. For flat concrete tiles, these roof
anchors are attached directly to the
roof rafters (rafter-mounted
installation).
Caution:
Never attach safety harness to the
installation system!
2. Expose the area above the rafters.
For roof anchor intervals, see page
8, 3.1 On-Roof System.
Note:
As a rule, pushing up the roof tiles
is sufficient. Horizontal positioning
of roof anchors is dependent on the
rafters and the tile valleys.
3. Place roof anchor (03-B) in line with
the top edge of the roof tile. Fix the
roof anchor to the rafter with screws
(16).
4. Fix all further roof anchors in the same
way. For roof anchor intervals, see
Page 8, 3.1 On-Roof System
installation.
Note:
Roof anchors must be horizontally
and vertically aligned (follow roof tile
valleys).
