Slackers Build-A-Branch Tree Swing Hanging Kit (Build-A-Branch) for 12–24 in Tree Trunks

What it is (and what it isn’t)

Slackers Build-A-Branch Tree Swing Hanging Kit is the part you’d buy when you already have a swing you like (or you’re planning to source one separately) and you need a reliable way to hang it from a backyard tree. The key detail: the kit is built around mounting to tree trunks—so you’re not setting up a dedicated swing set frame.

That also means it’s not “one box and you’re done.” A swing is not included, so if you’re picturing kids jumping on a finished swing immediately, you’ll want to confirm what swing seat/platform you’ll use with it before you order.

Key takeaways for buyers

If your yard has a healthy tree and you want a simple way to create a swinging spot, this kit focuses on fit and stability. On paper, you get a powder-coated, weather-resistant steel frame, plus hardware that uses a 360-degree swivel attachment so the seat can move naturally without binding.

It’s rated for a maximum weight capacity of 500 lbs. That number matters if multiple people will be on the swing at different times, or if you’re planning for heavier kids and adults to share the setup.

The kit is also designed for compatible tree trunks in the 12–24 in diameter range (37 in–75 in circumference). If your tree is smaller or larger than that band, it may not clamp down correctly, and that’s the kind of mismatch you don’t want to gamble on.

Worth noting: the brand description doesn’t mention a specific brand/model of swing, so compatibility will depend on the swing you plan to use.

Key features that affect day-to-day use

The powder-coated, weather-resistant steel frame is the “boring but important” feature. Outdoor hardware gets abused—rain, sun, and seasonal temperature swings—so having a corrosion-resistant frame helps keep the setup usable over time.

The 360-degree swivel attachment is another practical touch. Without a swivel, swings can start twisting awkwardly as kids bounce and turn. With a swivel, the motion feels freer and more natural, especially when kids spin or change direction.

And since the kit is compatible with tree trunks, installation revolves around selecting the right spot on the trunk and getting the connection secured to your tree properly.

What to check before you buy

Before you commit, there are a few “make-or-break” checks that are easy to overlook:

• Tree size: confirm your tree trunk falls within 12–24 in diameter (37 in–75 in circumference). Don’t estimate—measure.
• Weight capacity: remember the kit’s 500 lbs maximum capacity is the ceiling for the setup as a whole. If you plan to use it with a swing style that adds weight, keep that in mind.
• Swing not included: you’ll need a swing seat/platform that works with the hanging points you’re planning to use. If you don’t already have one, factor that into your buying plan.
• Mounting context: this kit is meant for outdoor tree trunks. If your tree is unstable, unhealthy, or the placement isn’t ideal, no kit can fully fix that.

Pros and limits (the honest balance)

What’s strong: the steel frame is described as powder coated and weather-resistant, and the 360-degree swivel is exactly the kind of feature you notice once kids start swinging and rotating.

What could disappoint: the absence of a swing in the box means you may end up doing extra shopping. Also, this is only a good match if your tree trunk falls into the 12–24 in diameter range—if your tree doesn’t, the whole plan may need to change.

So, if you want a turnkey “install and ride” solution, you might find yourself comparing this to more complete swing set options. If you already have a swing in mind and just need the tree-hanging hardware, it fits the job description.

Who it suits best (and who should skip it)

It makes sense if you have a suitable tree trunk in the listed range and you want a backyard swing setup without building a full frame.

It may not suit you if: - your tree trunk doesn’t match the 12–24 in diameter (or you don’t want to measure), - you need a fully included swing component right out of the box, - you’re looking for a more “set it anywhere” solution that doesn’t depend on specific tree fit.

How to use it (a quick, realistic scenario)

Let’s say you’ve got a healthy backyard tree and you’ve picked a strong trunk section where you want a swing to hang. You’d measure the trunk to confirm it sits in the 12–24 in diameter range, then use the kit’s hardware to secure the connection. Once it’s mounted, the swing (which you supply) attaches to the hanging setup, and the 360-degree swivel helps the seat move naturally as kids pump and rotate.

Is it worth it?

Buy the Slackers Build-A-Branch Tree Swing Hanging Kit if you already have (or plan to buy) a swing and you want the hanging system designed for compatible tree trunks in the 12–24 in diameter range, with a weather-resistant powder-coated steel frame and a 360-degree swivel attachment.

You may want to skip it if you expected a complete swing setup in one purchase, or if your tree trunk size doesn’t land within the stated diameter/circumference band. In other words: it’s a solid match for people building a tree-swing setup around a properly sized tree—but it’s not the easiest path if you want a fully turnkey solution without measuring and sourcing the swing separately.
