GTS Friend - Version 1.0:

Load Capacity - Set S
- in softwood up to 2.5 tonnes*
- in hardwood up to 6 tonnes*
* Important: The actual load capacity depends on many factors, e.g. lever arm, load direction or wood strength. Always calculate with a safety factor!
Lateral lever forces on the GTS Friend must be avoided, especially in softwood!

Assembly instructions & video
To install the GTS Screws, a hole must be pre-drilled in the tree – you can find the appropriate installation tools in our shop.
Detailed step-by-step instructions can be found on our YouTube channel.

Shipping & Delivery
I am extremely satisfied with TheTreehousShop. Great delivery service and the material is perfectly made. The tree house has made the fathers and children happy :-)
This kind of work requires good planning, creativity and patience. I even got to improve my carpentry skills 🙂 When we were done, we tested the treehouse by spending a night in it. The kids are absolutely thrilled!
The treehouse is mainly intended for our 8-year-old son Toni, but is now used by the whole family. Inside, there are two levels, a main room with windows on both sides and a cosy corner above.
Ideal for small projects & slender trees
Are you looking for a professional fastening for your children's playhouse? Then you've come to the right place. The adjustable triangles can be flexibly mounted in 1 or 2 trees. The load capacity is lower than with our large sets (M - XXL) – but ideal if only a thin trunk is available. Solid. Safe. Tree-friendly.
How it works – triangle mounting

Solution for thin trees < 35 cm (13.8 in)
To mount two triangles opposite each other, the trunk must be at least 35 cm thick at platform height – otherwise the GTS Screws will collide.
Solution for thinner trees: If the diameter is less than 35 cm, simply install the screws at different heights.

Leverage forces at a glance!
Important note: The GTS Friend (as the lower screw) is only suitable for low horizontal loads – especially in softwood. Avoid one-sided loads, lever and twisting movements. As soon as the trunk is large enough (> 35 cm), we recommend the stronger GTS Allstar!

Variable triangle angle
Unlike the Solid Tribeam Bracket with a closed back wall, the Vario Bracket allows you to freely adjust the strut angle from 90° (steep) to 120° (flat).
This makes it easy to avoid thick branches and gives you even more flexibility when designing your platform.
Successful projects
We love the little treehouses our customers build – get inspired, we have the right fastening for every tree!
Ask the Treehouse Pro
Need help? I'd be happy to advise you – please take a look at our FAQs first, as most questions are answered there ;)

Is my tree hardwood or softwood?
The higher the wood strength, the greater the load capacity of the tree bolts.
Information on the strength and wound healing of individual tree species can be found in Step 5: The right tree for your treehouse – including a table of the best trees for treehouses and their suitability for tree bolts.
Will my treehouse grow upwards with the tree?
Don't worry, you won't have to extend the ladder to the treehouse every year – your treehouse will always remain at the same height. Trees only grow upwards at the tips of their branches; the trunk grows in width. This growth in thickness (3–15 mm per annual ring) must be taken into account when building the platform!
Crooked tree? Build yourself a test triangle!

Slight inclines of less than 6° are usually not a problem – it is important to keep the lever forces low and align the main load so that the tree cannot tip over.
DIY tip: For crooked trees, build a test triangle out of wooden slats in advance and hold it in the tree – this will allow you to see immediately whether the triangle will fit your tree bolts later on.
Can I also use screws from the hardware store for Treehouse Fastening?
Our practical experience: No!
The screws, threaded rods and bolts available from DIY stores are not suitable for the extreme loads of a treehouse. The frequent alternating loads caused by wind are particularly problematic, as these can lead to fatigue fractures in normal wood screws over time.
In addition, the treehouse construction must be at a distance from the tree so that it can continue to grow in width. The distance and the associated lever forces can only be reliably handled by professional treehouse screws!
Are treehouse building instructions safe?
The internet is full of treehouse instructions and beautiful DIY videos – but be careful! Often, amateurish or tree-damaging attachment methods are shown, which in the worst case can even be dangerous.
