RAIL: Supports PV modules. Use at least two per
row of modules. Aluminum extrusion, available in
mill, clear anodized, or dark anodized.
RAIL SPLICE: Non structural splice joins, aligns, and
electrically bonds rail sections into single length of
rail. Forms either a rigid or thermal expansion joint,
4 inches long, pre-drilled (see page F). Anodized
aluminum extrusion available in clear or dark.
SELF-DRILLING SCREW: (No. 12 x ¾”) – Use 4
per rigid splice or 2 per expansion joint. Stainless
steel. Supplied with splice. In combination with rigid
splice, provides rail to rail bond.
L-FOOT: Use to secure rails through roong
material to building structure. Refer to loading tables
or U-Builder for spacing.
L-FOOT T- BOLT: (3/8” x ¾”) – Use one per L-foot
to secure rail to L-foot. Stainless steel. Supplied with
L-foot. In combination with ange nut, provides
electrical bond between rail and L-foot.
SERRATED FLANGE NUT (3/8”): Use one per
L-foot to secure and bond rail to L-foot. Stainless
steel. Supplied with L-foot.
MODULE ENDCLAMP: Provides bond from rail to
endclamp. Pre-assembled aluminum clamp available
in clear or dark nish. Supplied washer keeps clamp
and bolt upright for ease of assembly.
MODULE MIDCLAMP: Pre-assembled clamp
provides module to module and module to rail bond.
Stainless steel clamp and T-bolt. Available in clear
or dark nish.
MICROINVERTER MOUNTING BOLT: Pre-assembled
bolt and nut attaches and bonds microinverter to
rail. Washer at base keeps bolt upright for ease of
assembly.
NOTE - POSITION INDICATOR: T-bolts have a slot in
the hardware end corresponding to the direction of
the T-Head.

*w/Anti-Seize.
Anti-Seize*
Stainless steel hardware can seize up, a process
called galling. To signicantly reduce its likelihood:
1. Apply minimal lubricant to bolts, preferably
Anti-Seize commonly found at auto parts stores
2. Shade hardware prior to installation, and
3. Avoid spinning stainless nuts onto bolts at high
speed.
