• Overlapping back plate increases fastener strength and shear values, helping prevent post splitting
• Optimized screw patterns reduce splitting at the end of the post and maximize individual fastener capacity
• Extruded seat adds a greater cross-sectional steel section for added strength
• Teardrop holes allow higher and more even distribution of load
• Height: 27-7/8 in.
• Made from 10-gauge steel; galvanized (G90) for corrosion resistance
