CFI CFI Gate Installation & Hardware 1 — Questions and Answers
Question 1: What is the recommended minimum clearance between a gate frame and gate post on the latch side?
- 1/8 inch
- 1/4 inch
- 1/2 inch (Correct answer)
- 1 inch
Correct answer: 1/2 inch
A 1/2-inch clearance on the latch side allows the gate to swing freely without binding while still maintaining a close fit to deter intrusion.
Question 2: Why are gate posts typically set deeper and in larger-diameter holes than standard line posts?
- Building codes specify different depths for gate posts only
- Gate posts bear greater cantilever and swing loads that require extra stability (Correct answer)
- Gate posts must hold more concrete for appearance
- Deeper posts are required for hinge attachment
Correct answer: Gate posts bear greater cantilever and swing loads that require extra stability
Gate posts act as cantilever supports for the swinging gate load, generating much greater lateral stress on the footing than a static line post.
Question 3: Which hinge type is most suitable for heavy wooden double gates?
- Piano hinge
- Strap hinge
- Heavy-duty adjustable ball-bearing hinge (Correct answer)
- Continuous barrel hinge
Correct answer: Heavy-duty adjustable ball-bearing hinge
Heavy-duty adjustable ball-bearing hinges provide the load capacity and three-dimensional adjustment needed to keep heavy double gate leaves properly aligned over time.
Question 4: On which side of a gate are hinges always installed?
- The latch side
- The hinge post side (Correct answer)
- The center of the gate
- The bottom rail only
Correct answer: The hinge post side
Hinges are attached to the hinge post (the post on the pivot side), which is the fixed structural anchor that the gate swings from.
Question 5: What is the standard minimum number of hinges required for a 6-foot tall wooden gate leaf?
- 1 hinge
- 2 hinges
- 3 hinges (Correct answer)
- 4 hinges
Correct answer: 3 hinges
A 6-foot tall gate requires three hinges — top, middle, and bottom — to distribute the gate weight evenly and prevent racking or sag.
Question 6: What hardware component prevents a gate from swinging past 90 degrees and stressing the hinges?
- Gate latch
- Cane bolt
- Gate stop (Correct answer)
- Tension rod
Correct answer: Gate stop
A gate stop (or fence stop block) is mounted on the post to physically limit gate travel and prevent over-swinging that can damage hinges and the gate frame.
