- 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
- Installs with Strong‑Drive SDS Heavy‑Duty Connector screws (included)
- Extruded seat adds a greater cross-sectional steel section for added strength
