• The anchors must be screwed into
a support capable of bearing the
required static load (generally
rafters or concrete).
• Complies with the requirements of
DIN1055.
•
Roof batten height at least 1".
• The gap between rafter anchor
and top edge of the tile must be at
least 3-5mm. Under no
circumstances may the rafter
anchor be in contact with the tile
(if the overall height of roof batten
and tile do not match, the lower
height must be packed out).

Rafter anchor for roof tiles
#SRM20003 & #SRM20004
The rafter anchor is used for parallel and inclined mounting
on tiled roofs with a roof pitch of at least 15° and an area
loading greater than 6 lb/ft
2 . Can be used for various types
of roofing tiles.

Unpacking and checking parts
When unpacking the system, check the model names of the
components of each system and check to be sure you have the
correct number of parts (see FIG. 3-6).

WOOD SCREW (2X)
WASHER (M8) (1X)
HEAVY DUTY WASHER (2X)

Install rafter anchor
1. Determine roof type. Inspect the structural integrity of
the roof and the durability of the roof materials.
2. Determine the number of collectors needed for the
installation and the number of required roof attachments
from Table 3B or 3C on page 11.
3. Determine collector connection points (spacing).
Measure the spacing of the rafters or trusses to confirm
the dimensions and prepare for the system layout
(reference the Roof Attachment Spacing Section on
page 12).
4. Number two (2) tiles, one above the other. The upper
tile will be removed to install the rafter anchor.
5. Mark the edge of the upper tile on the lower tile to
ensure proper alignment upon assembly.
6. Using the rafter anchor as a template, pre-drill two (2)
6 mm holes, approximately 4 inches deep into the roof
substructure (see FIG. 3-7), perpendicular to the roof.

7. To achieve the recommended 3 - 5 mm clearance above the
tile, place the spacer plate(s) (provided in the kit) between
the rafter anchor and the roof substucture if necessary
(FIG. 3-8).
8. Place the rafter anchor on the spacer plate (if used).
9. Place the heavy duty washers over the holes pre-drilled in
Step
6.
10. Install the wood screws through the washers and rafter
anchor into the roof substructure.
Note: It may be necessary to grind the upper tile to assure a
better fit (FIG. 3-9).
