Survey the opening before choosing a hinge
For a service-yard gate, pedestrian entrance, or replacement leaf, first establish what must pass through the opening and how the gate will operate. Record the clear opening, leaf dimensions, weight, infill, opening direction, and required travel. Identify obstructions both above and below the gate's path.
Use EONE's gate hardware range to start a component schedule, not to bypass the survey. An adjustable hinge bracket may suit a custom mounting gap, while a latch and hasp set may address a separate closure detail. Neither selection establishes the adequacy of the posts or foundations.
Match the hinge to its supporting members
- Provide post and frame sections, wall thicknesses, mounting faces, and coating condition.
- Show hinge-axis position, offset, spacing, attachment method, and required adjustment range.
- Request the permissible application and rating basis for the exact hardware and assembly.
- Check access for installation, adjustment, inspection, and eventual replacement.
Gate width, infill, and exposure matter alongside weight. Do not select solely from a kilogram or pound figure without its test conditions and geometry. D&D's FAQ, for example, identifies pair-based ratings for its hinges and advises against increasing capacity by adding more. Confirm the arrangement actually supported by the selected supplier.
Resolve slope through operating geometry
Sloping pavement changes the clearance beneath a swinging leaf. Measure the travel path rather than checking only the closed position. A gate that clears at the latch post can still hit an uphill surface partway through opening. Review the geometry with the gate designer; changing hinge offset is not a universal solution.
For surface-mounted posts, provide the substrate, base-plate arrangement, and approved anchorage detail. For embedded posts, identify the supporting foundation design. Check drainage, settlement concerns, nearby curbs, and the space needed for equipment. Hardware adjustments cannot compensate for inadequate supporting construction.
Coordinate the latch and safety requirements
Specify the latch approach, handing, keeper position, closing gap, lock interface, and access from each side. State any required self-closing behavior separately; a hinge or latch should not be assumed to provide it. Match stops and holding devices to the approved gate design so ordinary closure parts are not expected to absorb every operating force.
Pool barriers, public access, emergency egress, and automated gates require applicable safety review. CPSC's automatic-gate guidance highlights entrapment hazards. A qualified installer or designer should establish current requirements, protective devices, and commissioning checks for the actual installation. No generic hardware kit makes the complete gate compliant.
Approve fit, then release the package
Arrange a sample review on representative post and frame sections. Check motion, adjustment, keeper engagement, finish clearance, and tool access. Record what was evaluated; a bench-fit approval is not a full-gate load or safety test.
Include hinges, latch parts, stops, fasteners, optional accessories, and spares as separate quote lines. EONE can review custom interfaces and coordinate a matched package. Door-to-door or site delivery can be arranged under the agreed quote, with access and unloading confirmed. Installation, crane service, duties, and unlisted accessories are not automatically included. Send the gate schedule and opening drawings for review.
