US Patent 12009774 L-foot adapter for rail-based solar panel racking systems

Described are supports with devices or brackets, that are specially mounted, such as L-foot adapters, that help mount solar panel racking systems to roofs. The L-foot adapter assembly may include an L-foot adapter body and a spacer that is removable and positionable between the two sides of the L-foot adapter body. A threaded fastener extends through the first of the two sides of the L-foot adapter body, through the spacer, and threadedly engages the second side of the L-foot adapter body. The spacer limits how much the two sides of the L-foot adapter body can be squeezed together and therefore prevents overtightening.
