014″ HD gate frameThe listing specifies 24′ of 4-inch heavy-duty USA aluminum gate-frame material for the Contractor Line assembly.
02Inner corner bracketsCorner reinforcement helps maintain a square, rigid frame as the two gate leaves are assembled.
03Channel kitThe channel system supports the horizontal ALU40 infill and creates a controlled, finished relationship between slats and frame.
046′ L-shape gate stopperThe listed L-shape stopper is part of the closing and alignment hardware for the double-swing system.
055″ two-way support hingeThe heavy-duty hinge system is selected for contractor-grade swing support and proper leaf alignment.
06Fastener setThe product listing identifies #10 × 1″, #12 × 2″ black and #10 × 3/4″ screws for the gate assembly.
07ALU40 horizontal slatsThe listed black infill is the ALU40 6′ profile. The matching ALU40 product specification identifies a 4″ × 3/4″ × 6′ profile, and this gate is offered with a 3/8″ or 1/2″ gap.
083″ HD post optionsOptional additions on the live product listing include 3″ × 3″ HD support posts in 8′ and 12′ options, plus matching 3″ aluminum caps. Final support selection depends on the site, footing, exposure and operator plan.
09Basic cane boltA basic cane bolt is listed with the gate kit for the double-swing closing and hold-open / hold-closed condition as appropriate to the installation.
11Custom project optionsCustom gate colors, sizes and slat spacing are available for project-specific orders, with optional HD posts and caps selected separately.
4″ HD frameThis Contractor Line configuration uses a 4-inch heavy-duty gate-frame platform for the 12-foot double-swing opening.
5″ two-way hinge supportHeavy-duty two-way hinge hardware is listed for the gate. Alignment and structural attachment remain critical across both leaves.
Post selectionThe live listing offers 3″ × 3″ HD post options in 8′ and 12′ lengths, with black and custom-color choices. Selection should match the actual opening, load, exposure, footing and operator plan.
Concrete and footing conditionsPosts must be installed plumb and securely supported. Footing design and embedment depend on project conditions and applicable requirements.
Automation planningThe gate can be planned for compatible swing automation, but operator capacity, attachment location, safety devices and site geometry must be confirmed as a complete system.
Center closing conditionBoth leaves must align correctly at the center, with the stopper, latch or access-control hardware planned before final adjustment.
Residential drivewaysCreate a modern two-leaf driveway entrance with wider 4-inch ALU40 horizontal lines and contractor-grade aluminum framing.
Estate entrancesThe broad 12-foot format works well where the entrance needs architectural presence as well as vehicle access.
Gated communities and HOA projectsUse the repeatable aluminum system where consistent appearance and durable gate construction matter across multiple access points.
Commercial accessA practical option for office, mixed-use and light-commercial entries when the opening and use cycle suit a double-swing system.
Pool and perimeter openingsThe horizontal aluminum system can be used at pool or perimeter access points when the complete installation, latch, clearance and local safety requirements are satisfied.
Light-industrial and mixed-use accessThe reinforced Contractor Line can serve appropriate light-industrial and mixed-use openings where the site conditions suit a double-swing gate.
Matching fence-and-gate packagesCoordinate the ALU40 horizontal language with compatible aluminum fence systems for a more continuous property design.
Coastal and humid climatesAluminum avoids iron-oxide rust and is well suited to environments where steel corrosion maintenance can become a recurring issue.
01Verify the finished openingConfirm the 12-foot overall opening, 6-foot gate height, grade, swing path and center meeting condition before setting support hardware.
02Confirm posts and footingsSelect the appropriate post configuration for the site, then install structural supports plumb, aligned and adequately founded for the gate and any operator loads.
03Assemble the 4″ HD framesLay out the heavy-duty frame sections, inner corner brackets and channel components on a protected flat surface and keep both leaves square during assembly.
04Install ALU40 4″ horizontal slatsInstall the 4″ × 3/4″ × 6′ ALU40 slats consistently using the ordered 3/8″ or 1/2″ gap and secure the system with the specified channel and fastener components.
05Set the 5″ two-way hingesHang and align both leaves so they swing freely, maintain clearances and meet correctly at the center without forcing the frame.
06Set stops, access hardware and automationComplete the L-shape stopper, latch or access-control condition, then test both leaves. If automated, commission the operator and required safety devices as a complete gate system.
01Measure the openingMeasure width and height at multiple points and confirm the finished dimension that the installed gate must serve.
02Check the swing arcConfirm both leaves have clear travel and will not conflict with vehicles, walls, landscaping, slope or required access paths.
03Select the support postsChoose the optional 3″ × 3″ HD support-post configuration based on actual structure, footing, exposure and gate-operator requirements rather than appearance alone.
04Plan automation earlyIf a swing operator will be used, select it before final hardware layout so attachment points, power, safety equipment and travel geometry are coordinated.
05Confirm slat spacing and privacyChoose the listed 3/8″ or 1/2″ ALU40 gap based on the desired visual coverage and openness, then confirm that configuration before assembly.
06Confirm finish and custom sizingThe black ALU40 slat specification identifies AAMA 2604 super-durable powder coating. Custom colors, sizes and slat spacing are available for project-specific orders.
