The QRail external and internal QSplices are used to join two rail
sections to provide a single rail section of a desired length.
5.2 QRail Preparation

For the Heavy or Standard rails, join the rail sections together
by sliding the QSplice onto the end of the rail, leaving half the
length of the splice protruding from the end of the rail.

Tighten the splice bolt onto the rail end. Tighten to 12  -lbf
(16 N-m).

Slide the other rail onto the splice and tighten the splice bolt
to 12  -lbf 16N-m).
External QSplice Installation
NOTE!
The QRail Internal and External QSplices are
a “full-strength” splice. Once it is installed
and tightened to the recommended torque
specification, it forms an essentially unbroken
rail.
It may speed installation to splice rails on the
ground and transport them to the roof in one
piece for installation on the roof attachments.
To allow for thermal expansion/contraction,
spliced rail lengths should not exceed 45 feet
without a thermal break of 1/2 in. or more. Do
not install modules over this thermal break.

DANGER
The outside edge of the
QClick must be installed
at least " from end or
rail at a splice location.

CAUTION
Spliced rails must have more than one
support on both sides of the splice.
Splices cannot be used in cantilever
areas.
