GTS Allstar 2.0 – Product Details
Dimensions & technical data
Load Capacity – GTS Allstar 2.0
Guidelines for the load capacity of the GTS Allstar 2.0 when loaded in the centre of the shank (lever arm 11 cm):
- Vertical: 1500 - 3800 kg
- Horizontal: 500 - 1300 kg
- Pulling out: 500 - 1000 kg
These values are guidelines - the exact load capacity depends heavily on the type of tree, lever arm and direction of load!
The load capacity should never be pushed to its limits!

Product innovations 2.0
- NEW – Tree Thread 2.0: The double-threaded thread was specially developed for living trees. The optimised thread shape maximises load transfer and facilitates installation.
- NEW – Quick Start Pin: The smoothed tenon allows direct insertion into the drill hole – for faster, effortless installation in the tree.
- NEW – Cylinder HL: The ‘Heavy Load’ cylinder (ø 74 mm) safely transfers extreme loads into the trunk. Four fine grooves mark the exact installation depth.
- NEW – Seal +: The expanding cylinder seals the drill hole and ensures a secure fit. The deep grooves facilitate natural wound closure during growth.
- Natural Transition: The tree grows over the screw. The parabolic transition supports this process and ensures harmonious integration – just like a natural branch!
- Shaft ø 40: With a diameter of 40 mm, the shaft can support all kinds of accessories and withstand the highest dynamic loads – maximum safety and a good night's sleep guaranteed.
- Seamless: No weld seams, no weak points – our innovative steel alloy makes GTS Screws indestructible.
- Black KTL-Coating: No rust! The environmentally friendly dip coating provides important corrosion protection. The black surface ensures a discreet, natural appearance in the tree.

Europe's best-selling tree bolt – Version 2.0
Whether you're building a huge luxury treehouse or a 10 m² (107,6 ft²) children's platform, we recommend the GTS Allstar for tree diameters of 35 cm (13.8 in) and above. With its large cylinder, it reliably transfers lateral forces into the tree trunk – a decisive factor when it comes to the dynamic loads involved in treehouse construction. The extra-long shank ensures a safe distance from the tree and leaves enough room for natural growth in thickness.
The vertical load capacity of 1,500 kg in softwood and up to 3,800 kg in hardwood (e.g. oak) guarantees maximum stability – even for the most demanding projects.
