The Angle Base is milled from solid aluminum to ensure a monolithic structure with predictable, superior strength hard coat anodized for protection and longevity. Bases are not cast or welded upon in any way to avoid unpredictable failure points. Angle Bases have 6 holes large enough to accept a 3” 16 penny nail for securing the bases to strongbacks and shoring lumber. The angle base is useful for when it is not possible to make full contact around the header or sole plate.
