Appendix C: Spacer Sticks
To assist in proper row and module spacing, PanelClaw makes Spacer Sticks available. These tools are
easily employed to ensure module supports are properly spaced in the array. To assemble the Spacer
Sticks please follow the directions below.
a.
Initial Claw Attachment to Module (One Module Only)
Place a PV panel face down on protected work surface
and place a Claw over the module frame flange on the
short side of the module; slide to the corner and tighten
the 3/8-16 x 1.0” 18-8 hex head cap screw between 18
and 20 ft-lb (24.4-27.1 N-m). Ensure that the Claw is
seated up against the flanges of both the long and short
sides of the module as shown in Fig. 16 below. Each
module must be fitted with four (4) Claws. This process
will be used later for attaching Claws to all modules.
b.
Spacer Stick - A
To set the Spacer Stick -A to the correct length, first
locate and remove the hardware from the longer, slotted
spacer stick. Next, measure the distance between the
protruding ends of the Claws attached to the long side of
the module (North-South) and add 1/8”. Then set the
Spacer Stick - A so that the slots in each end are at this
distance, Fig. 3 above.
c.
Spacer Stick -F:
Locate and remove the hardware from the shorter adjustable spacer stick with 3/8” studs.
Position, reinsert, and tighten locking hardware with the shorter spacer stick in the mounting
holes of the Claws on the short side (East-West) of the module.
