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.

Note:

indicates not applicable

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.
