- The BC40 is designed for a nominal 4x post size, making it suitable for standard 4x lumber used in decks, patio covers, and similar light structural applications.
- What fasteners should be used to install the BC40?
- Install with 16d common nails or #10 x 1-1/2 in. Strong-Drive SD screws. Always use all specified fasteners to ensure a proper, code-compliant connection.
- Can the BC40 be used for fences or unbraced carports?
