Our selection of composite deck posts is perfect for level decks, stair runs, and corner changes. VEVOR offers a wide range of blank and pre-drilled uprights in different heights and profiles, so you can mix intermediate, terminal, and angled units on the same project without searching for different brands. Season after season, powder-coated finishes do not rust, corrode, or fade from UV light. Our range includes everything you need to wrap a platform in your backyard, a rooftop terrace, or a business walkway, from the first post to the last tensioned run.
Are you planning to run a cable railing but are not sure which upright to put where? For a great layout, every deck needs a mix of corner units, angled stair uprights, and straight-line supports. You can get VEVOR composite deck posts in all three styles, and they all come in the same heights and finishes, so the handrail lines stay straight from the first post to the last return. You can skip the on-site guesswork and pick the configuration that fits your layout.
Getting the height and hole design right before the first bolt goes in will save you hours of work later. Before you order, here's how to read the specs on composite deck posts.
Most residential decks that are less than 30 inches above ground use 36-inch uprights. Higher decks, rooftop terraces, and most business walkways need 42-inch uprights. That extra six inches is not just for looks. It follows the guard height rules used by many local building departments during inspections, so make sure it fits your deck height before you place your order.
You should measure from the finished surface of your decking boards instead of the joists or frame, since composite boards raise your standard by about an inch. Even if the post is the right size at the frame, it might not be long enough once the boards are down.
When you mix deck heights, you get an uneven top rail line that you cannot hide. To avoid this, set a single height for the entire level run and treat the stair parts separately. Each floor of your deck will be the same height if it steps down to a lower lounge area. Always have two or three extra uprights on hand in case you forgot to include a corner in the first take-off. This is because returns and bump-outs usually require more posts than a rough sketch shows.
Pre-Drilled Cable Railing Pickets: This means that you can thread cable straight through intermediate positions without using a drill press or measuring on your knees. At the plant, spacing is always the same, which matters because holes of different sizes show up as sagging lines along a long run.
Blank Cable Deck Posts, also known as Non-Drilled Support Posts, let you handle the drilling. Choose these if your design calls for different cable spacing, if you want to use horizontal composite infill instead of cable, or if the upright is only there to support the structure behind a solid panel. They are also good for installers who want to match an existing fence with holes placed in an odd pattern.
Most projects use both. At the ends of a run, the terminal uprights usually need holes big enough for tensioners and fittings. In the middle, the uprights need only pass-through holes. First, count your runs, and then put them in the right order. People often make the mistake of ordering all pre-drilled units, only to find that the end positions require larger holes for hardware.
Level Deck Railing Posts are straight and sit flat on the deck surface. They cover all the straight edges of your deck. They are the most important part of any layout and make up about sixty to seventy percent of a typical order.
Machined 30-Degree Angled Stair Railing Posts have cable holes that tilt to follow the pitch of the stairs. This keeps the wires straight across the stringer instead of crossing it at an awkward angle. For most residential stair rises, a normal deck stair railing post cut at a 30° angle will work. Slightly steeper stairs may need field adjustments, though. Cables bind at the pass-through and tension unevenly without the angled hole design.
Corner railing posts in the shape of an L handle the 90-degree turns where two runs meet. Their shape lets cables terminate cleanly from both directions in a single upright unit, so you do not have to stack two separate units next to each other, which would take up deck space and look bad.
Before you place your order, draw your border and mark every change in direction. Count the number of corners, stair transitions, and terminals separately from the number of straight runs you have done.
On composite decking, the most common method is to mount posts through a base plate to the surface. The plate spreads the weight over a larger area, but it can only do its job if solid blocking or a joist is directly below. Never anchor only into decking boards. Over time, composite material can't handle the tension loads from a cable run.
Using fascia mounting bolts to attach the upright to the outside rim joist keeps the deck's surface clear and makes smaller platforms look better. For this method to work, the through-bolts and backing screws inside the rim must be longer.
Before you start installing, make sure the diameter of your lag bolts or carriage bolts matches the hole diameter in the base plate. When fasteners are too small, they let small movements happen that slowly loosen the whole run and make your wires less tight. At the terminals, where cable tension can exceed 200 pounds per line, a steel railing post transmits real force.
If at all possible, plan blocking during framing. Adding blocking under finished composite boards after the fact means removing and reinstalling the decks, which is much more work than adding a few blocks at the start.
The profile dimensions indicate which hardware will fit and how the finished railing will look. These composite deck posts come in a few standard sizes, each suited to different lengths and design goals.
2x2-inch square railing posts are the most common choice for structural posts at ends and corners where cable tension builds up. If you tension six or eight wires at the same time, the top rail stays straight because the walls are thicker and do not bend over long distances.
1x2-inch cable railing pickets are thinner supports that go between the main uprights. They keep sightlines open because they only guide the cable and do not anchor it, which is the whole point of a cable system on a deck with a view. By placing intermediates every 3 to 4 feet, you can hide the wire sag.
People who use metric units can find 2.5x5 cm Cable Handrail Posts with the same profile as 1x2 inch posts. Since the sizes are the same, do not order both versions thinking they are different. Compare the stated wall thickness with the outside dimensions, since two uprights with the same outside dimensions can behave very differently under load.
Most systems use 1/8-inch or 3/16-inch stainless steel wire, and holes are machined in advance to fit those diameters while leaving enough clearance for the cable to pass through smoothly. Before ordering hardware separately, make sure the hole size on the metal posts you choose for your cable railing matches the cable and fitting stems.
Because swage fittings and turnbuckles are wider than the cable itself, openings in terminal positions need to be bigger than openings in intermediate places. If you buy metal deck posts for cable railing as terminal units, they will account for this. But if you drill your own blank uprights, the openings will not be larger unless you increase the bit size at the ends.
Most posts are powder-coated black, which goes with both light and dark deck tones. Whenever possible, order all railing posts for a job at once, since finish batches can vary slightly. If you want to add a metal handrail post to a section of stairs later, you should ask for the same finish code.
They come in 36- and 42-inch heights and 2x2 and 1x2 profiles. VEVOR composite deck posts offer the full range in one place, including level, angled, and corner units, plus pre-drilled and blank options. That means you can place one order for straight runs, stair sections, and corner returns. You will not have to mix sources or finishes. On larger decks, competitive pricing keeps material costs low, and quick customer service backs up every purchase. Browse the collection now to build a railing that lasts for years and looks great.
Most decks that are more than 30 inches above ground need uprights that are 42 inches tall, while most lower platforms can get by with 36-inch uprights. Check your local building code, as inspection standards and guard height requirements vary by location.
Yes. If you need to change the structure or the distance between cables, you can drill holes in blank units in the field. Mark the same spacing between each hole with a metal bit, and smooth the holes so the wire can pass through easily.
Of course, angled posts are needed for cable systems. Machined holes in angled units follow the pitch of the stairs and keep the wires straight along the stringer. Level uprights push wires through at an angle that can bind them, leading to uneven tension and premature wear.
Intermediate posts should be spaced about three to four feet apart. Cables can sag between supports when the holes are bigger. Places like corners and ends of lines carry tension load, so they should always use the heavier structural profile.
Match the hole size to the wire size, which is usually 1/8 or 3/16 inch. Before you buy, make sure both measurements are correct. The terminal openings need to be big enough for both the fitting bodies and the cable.
