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 ALU20 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.
07ALU20 horizontal slatsThe listed infill profile is ALU20 at 2″ × 3/4″ × 6′. Slat spacing should match the ordered configuration and project requirements.
08Post optionsCompatible post options shown on the current listing include 2″, 2.75″ and 2″ × 3″. Final selection depends on site, footing and operator conditions.
09Custom project optionsCustom colors and custom gate sizes are available, allowing the Contractor Line system to be specified beyond the standard 12′ × 6′ configuration.
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 selection2-inch, 2.75-inch and 2 × 3-inch post options are shown on the listing. Selection should match the actual opening, load, exposure 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 support 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 horizontal ALU20 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 ALU20 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 ALU20 horizontal slatsInstall the 2″ × 3/4″ × 6′ ALU20 slats consistently according to the ordered spacing and secure them with the specified fasteners.
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 among the listed post options 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 privacyThe ALU20 system can balance privacy and airflow through the ordered slat spacing. Confirm the actual configuration before assembly.
06Confirm finish and custom sizingAAMA 2604 architectural powder coating is standard to the system, with custom colors and custom gate sizes available for project-specific orders.
