Planning & choosing a kit
What does this pedestrian gate installation guide cover?
It covers field assembly and installation of the Alumission horizontal aluminum single-swing gate shown in the video, including side posts, slats, hinges, lock and stopper. Use your selected kit’s current instructions and fitting limits. A driveway, sliding or double gate needs its own guide.
Can I install an aluminum gate kit myself?
A capable DIY installer with accurate measuring, metal-cutting and drilling experience can assemble the kit. Hanging the leaf is easier with a helper. Get professional help for uncertain supports, structural anchorage, difficult cuts or regulated pool and exit applications.
Does the gate need welding?
The demonstrated Alumission kit uses mechanical assembly with screws and captured slats. No field welding is shown. Prepare clean cuts, square the frame and use the specified fasteners; welding is not a substitute for correcting a poorly fitted connection.
Which size should I order?
Measure the finished opening and choose a kit that covers both your required width and height. Nominal kit dimensions describe fitting limits, not a ready-made gate leaf. Compare single swing gate kits and confirm the selected variation before purchase.
Can the gate open inward or outward?
The video demonstrates both stopper arrangements. Inward opening uses the side-post stopper on the latch side; outward opening uses covers on both side posts and a stopper attached to the gate frame. Establish swing direction and hinge handing before drilling.
How long will assembly take?
The roughly 15-minute video demonstrates the sequence, not the project duration. Support preparation, cutting, lock drilling, finish protection and final alignment all take time. Allow extra time for a first installation and avoid promising a fixed completion time before inspecting the site.
Can this be used as a pool gate or an emergency exit?
Do not assume a standard kit and keyed lever meet those requirements. Confirm the applicable barrier or exit rules, opening direction, latch location, self-closing performance and hardware suitability with the local authority and project professional before ordering or drilling.
Measurements & cutting
How long should I cut the horizontal slats?
For the system in the supplied video and corrected Alumission guide, cut the slats 8 inches shorter than the actual clear opening between the installed side posts. Confirm that the current profiles match this detail, and test one cut before cutting the entire batch.
Is the allowance 7-3/4 inches or 8 inches?
Use the corrected 8-inch allowance for this assembly. The current illustrated product guide expressly corrects Part B, Stage 4. Do not combine an older 7-3/4-inch instruction with this video’s system.
Do I measure between columns or between side posts?
Measure the clear space between the installed aluminum side posts. The raw opening between masonry columns is a different dimension because the side posts occupy part of it. Do not apply the 8-inch subtraction to an outside-to-outside or nominal kit measurement.
What if the top and bottom widths differ?
Check the side posts for plumb and alignment before cutting. The video uses the smaller measurement for a difference up to 1/4 inch and calls for post correction with suitable plastic shims when the difference is larger. Correct the underlying support or fixing issue rather than forcing a tapered gate into place.
How much ground clearance do I need?
The video’s example makes the gate frames 1–2 inches shorter than the side posts. Establish the actual finished gap from the complete swing path, surface slope, hardware and any applicable barrier requirements. An uphill swing may need more clearance; a regulated barrier can limit the allowable gap.
Can I cut down the width and height?
The kit is cut to fit within its permitted size range. Plan frame length, slat length, cap position, spacer pattern and any ripped final slat together. Confirm a particularly narrow or short layout with Alumission before cutting away needed lock or hinge space.
What blade and cutting setup should I use?
Use equipment and blades rated for the specific aluminum profiles, support long pieces and clamp work securely. Keep guards in place, deburr cut edges and clear chips promptly. Follow the tool maker’s instructions rather than copying a hand position from a video.
Posts, supports & anchors
Can I attach the gate to a wall or masonry column?
Yes, when the underlying support and selected anchors are suitable for the gate loads. The video attaches aluminum side posts to existing columns. Check material, condition, anchor embedment, edge distances and fastening locations; a decorative veneer alone is not a sufficient support specification.
Which anchors or screws do I need?
Choose them for the actual concrete, masonry, wood or structural metal support and the gate load. The aluminum assembly screws do not replace those site-specific fixings. Follow the chosen fastener’s drilling, cleaning, engagement and tightening instructions.
Why do the side posts need two different hole sizes?
The larger channel-side hole provides access for driving the fixing. The smaller back-wall hole suits the anchor or screw connection. In the video the 3/4-inch cutter passes through the first wall only; do not enlarge both walls to that access diameter.
How many side-post fixings are required?
The video demonstrates four to five access positions per post, but that is not a universal engineered anchor schedule. Confirm the number, spacing and support arrangement for your gate, height, exposure and substrate before drilling.
Can I use an existing chain-link or thin metal fence post?
Do not assume compatibility from post diameter or appearance. A pedestrian gate adds hinge, closing and wind loads. Have the existing post, wall thickness, foundation and proposed connection assessed, and obtain an appropriate mounting detail before reusing it.
What if a roof or column cap blocks a sliding cover?
Plan cover insertion before securing surrounding parts. The video shows dividing the cover into shorter sections that slide into place sequentially when overhead access is limited. Check that the pieces seat properly and preserve the finished appearance; do not damage the column cap to force a full-length cover in.
Does this guide explain new concrete gate foundations?
This video begins with suitable existing supports. New freestanding gate posts and foundations need a separate design for soil, frost, wind and gate loads. The fence-in-soil guide explains foundation planning, but its fence details are not automatically a gate-post specification.
Slats, frames & hinges
Which parts should I check before starting?
Check side posts, gate frames, their covers and caps, slats, style-specific spacers, hinge hardware, lever/lock and the appropriate stopper. Quantities change with size and style. Compare the order’s parts list; mounting anchors, tools and a lock-drilling jig should not be assumed included.
How do I keep the gate square while assembling it?
Seat the first slat fully against the capped frame ends and check both corners with a quick square before fastening. Work on a protected stable surface. Recheck alignment and gaps after hanging, because the video includes a final supported adjustment stage.
Should every slat be screwed in immediately?
Follow the video’s staged assembly and adjustment sequence. It secures the initial and final slats for handling, then adjusts the supported gate before adding the remaining required connections. The video recommends slat fixing intervals of 6–12 inches; follow any updated kit detail.
What if a spacer or slat will not slide in?
Check that the profiles match and inspect for burrs, chips, distortion or an incorrect cut. Seat parts gently with a rubber mallet only as appropriate. Do not force a jammed component or damage the finish to hide a sizing problem.
Which way does a ripped final slat face?
The video temporarily assembles with the cut/open edge up, fits the caps, then flips the leaf so that edge becomes the bottom. Follow the actual sequence at 6:29–7:43 and confirm the intended final orientation before fitting the lock or hinges.
Where do the hinges go and how many are needed?
The video positions hinges within 12 inches of the top and bottom, with the adjustment openings upward, and adds a center hinge for applicable larger gates. Use the quantity, spacing, handing and capacity required for your supplied hardware and selected gate.
How do I adjust self-closing hinges?
Use the supplied hex key and retaining pins exactly as directed on the hinge instructions. Start with suitable alignment and a freely moving leaf, then adjust and test closure. Do not add tension to compensate for binding, loose supports or a misaligned strike.
Locks, latches & stoppers
Is 2-3/8 inches the hole-saw diameter?
No. In this video, 2-3/8 inches is the backset: the distance from the latch edge to the center of the face bore. The face hole saw is 2-1/8 inches and the latch hole saw is 1 inch. Always confirm your particular lock’s template before drilling.
Is the lock-drilling jig included?
The video explicitly identifies the door-lock installation kit as a separate tool. Select a jig and hole saws suitable for your metal frame and lock. Check the order contents rather than confusing the supplied lever hardware with the drilling equipment.
How high should the lever be?
The video mentions 42 inches as an ordinary example where special requirements do not apply. Determine the actual location from the intended use, accessibility, pool or exit requirements and the chosen hardware. Mark it only after checking the gate’s finished height.
Can I fit a deadbolt, keypad or smart lock?
Check frame depth, backset, bore layout, edge clearances, handing, outdoor rating and power requirements for the exact model. A lock that fits a standard door is not automatically suitable for an exposed gate. Confirm fit before adding irreversible holes.
Why will the latch not catch?
First inspect gate alignment, hinge movement, clearance and the strike position. Mark the strike from the fitted latch with the leaf in its final closed position. Correct binding or sag before enlarging holes or moving the strike to compensate.
Which stopper do I use?
For the arrangement shown, inward opening uses the side-post stopper; outward opening uses the gate-frame stopper. The latter is trimmed and notched around the latch near the end of the video. Do not install both simply because both profiles are supplied.
What tool makes the screw-head pockets in the stopper?
Use a compatible countersink tool or suitable larger metal bit to form the shallow recess specified for the flat-head screws. This is separate from the pilot hole. Control the depth so the screw head seats correctly without weakening the profile.
Troubleshooting, care & help
Why does my gate sag after hanging?
Check whether movement comes from the supporting post, anchors, hinges or assembled frame. Support the leaf before adjusting anything. Follow the video’s supported frame-alignment sequence only after confirming that the posts and hinge connections are sound.
What if the gate rubs against the ground?
Check the entire swing path, including high spots and uphill paving, along with hinge alignment and frame height. Correct the cause and preserve the permitted clearances. Do not simply increase the bottom gap on a regulated barrier without checking its requirements.
Can I fix alignment by reusing the same screw holes?
The video directs the installer to refasten through different holes after the frame adjustment. Oversized or stripped holes will not provide the original connection. Ask technical support for the appropriate repair if a fixing location is damaged.
How do I protect the powder-coated finish?
Use padding, masking tape where appropriate and clean supports during assembly. Remove metal chips without dragging them across the coating. Deburr exposed cuts and use the compatible touch-up treatment recommended for the finish.
How should I clean and maintain the gate?
Use mild soap, water and a soft cloth in line with the finish-care instructions. Inspect caps, screws, hinges, anchors, stopper and latch periodically, and after unusual impact or movement. Follow the hardware manufacturer’s lubrication and adjustment directions.
Can I use this guide for double or sliding gates?
Use the relevant system guide instead. Double gates add meeting gaps, stops and potentially drop bolts; sliding gates use tracks, guides and catchers. Start from the Alumission installation library for the matching assembly.
What should I send for technical help or a quote?
Send the opening width at the top and bottom, desired height, swing direction, support material, ground slope, ZIP code and clear photos. Include the kit or order number and any pool or exit use. Contact technical support before cutting if any measurement or hardware detail is uncertain.
