Which practice best helps ensure posts remain upright and gate frames square during installation?

• A. Ensure posts are plumb, use level hardware, and square frames
• B. Lean posts and misalign frames
• C. Use non-square frames
• D. Skip checks at installation

Answer: (A)

The main idea here is maintaining vertical alignment and true geometry during installation so the gate works smoothly and stays square over time. Keeping posts plumb ensures each post stands perfectly vertical, so the gate hangs in its designed plane instead of leaning and pulling the latch out of alignment. Using level hardware means the hinges and latch sit on a flat, true plane, preventing binding or uneven gaps as the gate swings. Making sure the gate frame is square guarantees the corners are right angles, so the hinges align cleanly and the latch lines up when the gate closes. When all three are done—posts perfectly vertical, hardware level, and frame square—the gate will swing freely, close properly, and remain upright and true.
