WEEB stands for "washer, electrical equipment bonding." WEEB 9.5 NL products are used to bond solar modules to aluminum solar mounting rails. The mounts are then grounded, grounding the entire assembly.

This is the 3/8" hole washer with no legs (NL) that mounts between the strong back on your Top-of-Pole Mount and the rail which electrically bonds the rail to the rest of the rack.

This eliminates the need to use a lay-in lug and thread-forming screw on each module and it eliminates the need to run a continuous wire to each module. This saves time and money and it meets the requirements of UL 467. Wire is only needed to connect a lay-in lug on each module rail to an equipment grounding terminal in the inverter or disconnect. ETL listed to UL standards.
