When installing a diagonal brace on a gate, the miter cuts should contact which parts of the gate?

• A. The vertical frame board at the hinge side and the top rail at the latch side
• B. The bottom rail and latch post
• C. The center rail and top post
• D. The hinge post and bottom rail

Answer: (A)

When a diagonal brace is added to a gate, its ends should bear against solid frame members so the brace can transfer loads effectively and keep the gate square. The best placement is one end against the hinge-side vertical frame board and the other end against the latch-side top rail. This creates a strong triangle with the gate’s frame, giving resistance to racking and preventing the gate from twisting or sagging under wind or push forces. The hinge-side vertical member provides a sturdy fixed edge, while the latch-side top rail offers a solid mounting point high in the frame, where twisting forces are most likely to act. If the ends were set on other members, like lower rails or less solid posts, the brace wouldn’t provide the same rigid triangulation and the gate would be more prone to misalignment or movement.
