SM LIGHT RAIL
SM STANDARD RAIL
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 a rigid splice joint, 4
inches long, preassembled with bonding hardware.
Available in dark anodized or mill nish.
L-FOOT: Use to secure rails through roong
material to building structure. Refer to loading
tables or U-Builder for spacing.
L-FOOT T- BOLT: (3/8” x ¾" or 1”) – 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 L-foot and rail.
SERRATED FLANGE NUT : Use one per L-foot
to secure and bond rail to Lfoot. Stainless steel.
Supplied with L-foot.
MODULE ENDCLAMP: Pre-assembled universal
clamp that secures module to rail at module
ange by tightening 1/2" hex head bolt.
MODULE MIDCLAMP: Pre-assembled clamp
provides module to module and module to rail
bond. Aluminum clamp with stainless steel
bonding pins and T-bolt. Available in clear or
dark nish.
MICROINVERTER MOUNTING BOLT:
Preassembled bolt, nut, and captive star washer
attaches and bonds microinverter to rail.
NOTE - POSITION INDICATOR: T-bolts have a slot
in the hardware end corresponding to the direction
of the T-Head.
Wrenches and Torque
Stainless steel hardware can seize up, a process called
galling. To signicantly reduce its likelihood:
1. Apply minimal lubricant to bolts only where
indicated in installation process, preferably Anti-Seize
commonly found at auto parts stores (Anti-seize has
been factory applied to mid clamp bolts)
2. Shade hardware prior to installation, and
3. Avoid spinning stainless nuts onto bolts at high speed.
