6.3 Installing the End Modules
The end modules of the PV system are fastened on the outer side with two module end clamps each. Three types of module
end clamps are available from Quick Mount PV. Fixed end clamps are sized to fit a particular module thickness and will
not work on modules of other thicknesses. Hidden end clamps will work on any module with a flange in the acceptable
clamping zone. Universal end clamps are designed to fit 2 ranges of
module thicknesses. Universal end clamps are available in the following
size ranges:

30-45mm

38-50mm
Mounting Steps, Fixed Height End Clamps:

Place and align an outside module. The QRail must extend beyond
the module frame by a minimum of 1.2 in.

Insert the QClick of the end clamp into the channel of the QRail.

Push the module end clamp flush to the module frame.

Tighten the bolt to 8  -Lb (11 Nm), thus clamping the module.
Mounting steps, Universal End Clamps:

Place and align an outside module. The QRail must extend
beyond the module frame by 1.2 in. (30 mm).

Insert the QClick of the end clamp flush against the module
frame. The lip of the upper clamp body should be flush against
the edge of the module.

Ensure that the lower section of the clamp body sits squarely on
the top of the rail.

While holding the upper clamp body against the module and
the lower clamp body, tighten the clamp bolt to 8  -lbf (11
N-m).
DANGER
Material damage due to incorrect installation
Incorrectly mounted clamps with QClick Technology can slip out. PV modules can fall and be
damaged. Mount all clamp connections in accordance with the instructions.
 Make sure the clamps are installed correctly.
 Ensure the module is installed flush and tight against the side of the end clamp.
 Ensure proper torque of the end clamp mounting bolt 8  -lbf (11 N-m) or 9 -lbf for hidden
end clamps.
