Installation of the QRail system on most roof-types requires that any penetrations of the roof system be flashed in
accordance with the appropriate local codes and roofing best practices.
5.3 QRail Installation on Roof-top
•
Aer determining the location of the array on the roof, mark the rail locations with chalk lines or other suitable method.
•
Determine the raer locations and mark them on the E-W chalk lines.
•
For standard rail configuration installations, install roof attachments per the mount manufacturer’s instructions.
•
Install the roof attachments with mounting brackets along the chalk line per the manufacturer’s instructions. For raer
attached systems take care to align the mounting point (mount bolt) as closely as possible to the intersection of the
raer and the chalk line.
•
Loosely install the T-bolts on the mounting bracket with the T-bolt facing the rail channel. The mounting bracket may be
aligned any direction.
•
Position the rail in place and hold each end of the rail against the end mounting bracket. Insert the pre-assembled T-bolt
rail fasteners in the end mounting bracket into the slot on the side of the QRail. Set and hold the rail level at the desired
height by moving the T-bolt up or down in the mounting bracket.
•
Using a " or 13 mm socket, tighten the rail fastener nuts to 192in-lbs (22 N-m).
Be sure to allow the bolt head to rotate as far as possible in the T-bolt channel
to ensure full engagement of the bolt head with the sides of the channel. Full
engagement is confirmed when the alignment line on the end of the T-bolt is
vertical.
•
Proceed along the line of mounting bracket, inserting the T-bolts and tightening as
above.
•
Repeat the above steps for each rail in the array.
Installing Standard Rail Configuration
NOTE!
If rails are to be spliced, the splice should be
installed prior to installing the rails onto the
L-feet or other roof attachments. See Section
5.2 for rail splicing instructions.

T-bolt correctly positioned for insertion
INCORRECT CORRECT
DANGER
Rail must be installed so the mount is
fully engaged (edge of rail line to line
with edge of mount) and maintain a
minimum of 3/4” from the end of the rail
to center of T-bolt.
