Determine Two Screws or One Screw Installations of Tilt Legs
There are options of using two screws or one screw for installations of adjustable and fixed tilt legs, depending on the
project scenario, such as required interface spacing, purlin spacing, rib spacing of roof sheet and so on. Please find
note 22 of engineering letter for details.
Determine the Maximum Rail Support Spacing
Please refer to the Certification Letter and Tilt Legs Spacing Table. If a project specific Certification Letter has been
provided, please refer to the support spacing in this letter.
Verify Maximum Rail End Overhang
Rail end overhang should not be over 40% of the Tilt Legs spacing. For example, if the Tilt Legs spacing is 1500mm, the
Rail end overhang can be up to 600mm only.
The application of Adjustable Tilt Legs
Following the tilt angle rules of Determine Roof Slope and Tilt Leg Angle on the north or south facing roof, the actual
panel tilt angles using the adjustable tilt legs installed at the different purlin spacing could be applicable or not. Please
see the table and side view diagrams below.

The table above is based on:
1. The panels are clamped within one quarter of panel length;
2. Rear leg adjustable range: ER-TL-10/15: 260-375 mm; ER-TL-15/30: 390-635 mm; ER-TL-30/60: 675-1205 mm;
3. If the info. is different from the table and diagram, it could have different results. Please contact the Clenergy to
confirm its applicability.
