When installing a diagonal brace on a wooden gate, where should the lower end be located?

• A. At the hinge post
• B. At the latch side
• C. In the center of the gate
• D. At the top rail

Answer: (A)

A diagonal brace on a wooden gate functions as a rigid support that transfers the gate’s weight and wind loads to a fixed anchor, helping to keep the gate square and prevent sag over time. The lower end should be at the hinge post because this corner is the fixed, load‑bearing point of the frame. Placing the brace there lets the member pull from the hinge side upward toward the latch side, forming a stable triangle that converts downward force into a compressive force along the brace and into the hinge post. This setup resists the gate sagging away from the hinge and maintains proper alignment as the gate swings and as environmental forces act on it. If the lower end were at the latch side, center of the gate, or the top rail, the brace wouldn’t anchor where the load originates, so it wouldn’t effectively counteract sag or keep the gate square.
