WEEB stands for "Washer, Electrical Equipment Bonding". The WEEB family of products are used to bond solar modules to solar mounts. The mounts are then grounded so the entire assembly is grounded.

The WEEB-11.5 is a washer used to bond PV module mounting brackets to Power Beam Rail. Use at least one WEEB-11.5 under every mounting bracket and joiner bracket. Use more than one when that bracket joins two or more separate rails together. Place one WEEB-11.5 on the T-bolt of each individual rail, under a module mounting bracket, or joiner bracket.
