The AndyMark Walnut Extrusion 2 x 1 11.25in. Black is a robust structural component designed for constructing strong, right-angle joints without the need for gussets. It features a 2x1 profile with an end profile accommodating six holes for 1/4-20 thread-forming screws, arranged in a 5/8 inch square grid pattern. The extrusion includes rib supports that enhance strength and prevent damage from over-tightening. The anodizing process may cause slight color variations from the reference image, described by the FED-STD-595 color system.
