The best side mount deck railing depends on your layout, preferred railing style, and whether you need a level-deck or stair system. For a cable design with a 36-inch height, compare the two Muzata kits by coverage length. Egadis is an aluminum option for buyers who prefer a solid modular railing, while PLANTOP is specifically configured for right-sided stairs. Gyykzz offers a taller, all-black cable system with included cable and posts. Check local building requirements and the product’s installation details before choosing.

Muzata 16–20 ft RW21 Cable Railing Kit
This 36-inch modular cable railing kit is best for homeowners planning a longer level-deck run and wanting a less obstructed view. Its hidden side-mount bases are designed to save deck surface space, and the listing describes a corner post intended for inside or outside corners. The set includes hardware and connectors, plus a printed guide and step-by-step video.
The kit is selected for its stated 16–20-foot coverage range and modular layout. Muzata advises keeping post spacing at or below four feet. Limitation: A handrail is not included, so account for that separately when planning the system.
Egadis 6 ft Modular Aluminum Railing Kit
This two-pack is best for buyers seeking a black aluminum railing rather than cable infill. Each section is listed as 36 inches high and six feet wide. The side-mount design attaches at the deck edge, which can preserve usable deck surface, and the product description highlights a clip-on modular design and a low-maintenance powder-coated finish.
Egadis describes the finish as AAMA 2604 and states that it is designed to resist rust, corrosion, UV exposure, and weather. This pick suits decks, porches, balconies, and rooftop patios where a solid railing style is preferred. Limitation: The listing’s two sections provide a fixed combined length; measure the run and corner layout before selecting a kit quantity.
Muzata 12–16 ft RW21 Cable Railing Kit
Choose this 36-inch Muzata kit if your level-deck project needs a shorter cable railing run than the 16–20-foot version. It uses a space-saving side-mount profile with hidden bases, and the listing includes hardware, connectors, a paper guide, and an installation video. The modular format is intended to work with separately selected handrail styles.
This option is best for buyers who want the RW21 cable system but need a stated coverage range of 12–16 feet. Keep the manufacturer’s post-spacing guidance of no more than four feet in mind when measuring. Limitation: The handrail is not included, so verify the complete system requirements before ordering.
PLANTOP MY10-SP Right-Side Stair Kit
This PLANTOP kit is best for a right-sided staircase that needs side-mounted posts. The listed configuration covers 4–12 feet and is designed for stair angles of 25–35 degrees. Its two black posts are made from T304 stainless steel with a matte black powder-coated finish. Included 1/8-inch cable uses swageless fittings, so the described installation does not require hydraulic crimping.
The side-mounted stair posts attach to the fascia to avoid occupying tread space. The listing also describes rubber grommets and says the posts can serve as structural end or middle posts. Limitation: This is a right-side stair configuration, not a general-purpose level-deck kit; a handrail is not included.
Gyykzz 12–20 ft 42-inch Cable Kit
Gyykzz is best for buyers seeking a taller, black side-mount cable system with posts and cable included. The listing specifies four level posts, 24 swageless cable kits, 249 feet of T316 stainless steel cable, rubber grommets, a cable cutter, and an installation guide. It describes the posts as T304 stainless steel with a matte black coating and welded side brackets.
The stated coverage is 12–20 feet, and the listing says the swageless fittings do not need a hydraulic crimper. Limitation: The handrail is not included. Confirm the 42-inch system height matches your project and applicable local requirements.
Buying Guide: How to Choose Side Mount Deck Railing
How much railing length do you need?
Measure each straight run and note corners, stairs, and transitions before choosing a kit. The Muzata options cover different stated ranges: 12–16 feet or 16–20 feet. Egadis is sold as two six-foot sections, while PLANTOP is listed for 4–12 feet of stair installation. Compare the product’s coverage with your actual layout rather than relying only on the number of posts.
Should you choose cable or aluminum infill?
Cable systems suit buyers who prefer a more open-looking railing, while the Egadis kit uses modular aluminum railing components. Cable kits may require careful planning for post spacing, cable routing, and handrail selection. The aluminum option avoids cable assembly, but its fixed section dimensions may require a different quantity or layout for your deck.
Is the kit for a deck or a staircase?
Check whether the product is intended for level runs, stairs, or both. PLANTOP’s listed posts are specifically for right-sided stairs with a stated 25–35-degree range. The Muzata kits are described for decks and include guidance for post spacing. Do not assume a stair kit or level kit fits a different orientation without checking the installation instructions.
What else should you verify?
Confirm the mounting surface, post spacing, corner requirements, included hardware, and whether a handrail is supplied. Compare the product’s dimensions with local building codes and your project plans. Product descriptions are not a substitute for confirming code requirements or the suitability of the deck structure for the planned installation.
Frequently Asked Questions
What does side mount railing mean?
Side mount railing attaches to the side or fascia of a deck rather than sitting on top of the deck surface. This layout can preserve more usable deck space.
Do these kits include a handrail?
The Muzata and Gyykzz listings state that handrails are not included. The PLANTOP listing also says its handrail is not included. Check the Egadis package details before ordering if a specific top rail is required.
Can I use a stair railing kit on a level deck?
Not necessarily. Stair kits may be designed for a particular side and angle. For example, PLANTOP specifies a right-sided staircase and a 25–35-degree range.
How far apart should posts be?
Muzata advises that post spacing should not exceed four feet for its RW21 kits. For other products, follow the provided installation instructions and applicable local requirements.
