Modified shared rail configuration
The QRail internal QSplices are used to join two rail sections to provide a single rail section of a desired length.
5.2 QRail Preparation
NOTE!
The QRail QSplices are “full-strength” splices. Once a splice is
installed and when splice rules are followed it forms an essentially
unbroken rail.
To allow for thermal expansion/contraction on wooden
structures, spliced rail lengths should not exceed 45 feet without
a thermal break of " or more. Do not install modules over this
thermal break.
Other structures such as metal buildings and/or temperature
deltas other than 100°F could result in increased or decreased
thermal break calculations. If this is the case, site-specific
calculations may be used in place of a 45 foot thermal break.
DANGER
The outside edge of the QClick must be
installed at least " from end of rail at
a splice location.
CAUTION
Spliced rails must have more than
one support on both sides of the
splice unless conditions in the Code
Compliance Letter Installation Notes
are met. Find the Code Compliance
Letters at quickmountpv.com. Splices
cannot be used in cantilever areas.
•
The internal QSplice is a floating splice, no attachments
necessary.
•
To join any rail using the Internal QSplice, join the rail sections
by sliding the splice into the end of the rail until the bonding
plate tabs come into contact with the end of the rail.
•
Slide the other rail onto the splice until the end of the rail comes
in contact with the bonding plate tabs. Make sure that both
rail ends are tight against bonding plate tabs.
•
When re-installing the QRail Internal QSplices, insert the splice
backwards for optimal performance.
