US Patent 11802410 Rackable railing assembly

A rackable railing assembly including a rail having a hollow interior. A series of picket slots are disposed in the rail. A tab strip is carried in the rail. A series of tab slots are laterally spaced along the tab strip. A tab is secured at one end of each of the tab slots and extends partially across the tab slots so that the tabs are bendable in the tab slots. A series of pickets are included having a distal end portion extending through the picket slots in the rail and having an end surface secured against one of the tabs. The pickets pivot in the picket slots causing the tabs to bend relative to the plain of the tab strip to allow the pickets and rail to rack to an angle.
