The Static Support is the fixed connection of your wooden support beams with the GTS Tree Screws. Every treehouse, whether in a single tree or in a group of trees, needs this static fixed point.

Fastening to wooden beam
Secure your wooden support beam with our ready-made Screw Set. If the load is very high or strong leverage forces are to be expected, it is better to use ø 8 mm wood screws and ø 12 mm carriage bolts with thick washers.
So that the tree can continue to grow undisturbed, attach your support beams to the GTS at a distance from the tree. The greater the load and the softer the tree trunk, the smaller the distance and thus the lever arm should be. You can determine the exact position with our Distance Rings.
If you still want the maximum distance to the tree with a heavy load, reinforce your GTS with the Strut GTS +.
2 x Static Support
Double it up!
If your platform is subject to strong lateral rotational movements, e.g. in the case of a single-sided cantilever treehouse that is only fastened with a triangular construction, the Tree Screw – Support – Wood Screws connection will be subjected to strong shear loads! In this case it makes sense to double up the wooden beam in this area and to mount two Static Supports next to each other.
What is delivered?
1 × Static Support (without Wood-Screw-Set)
- DIN quality steel
- Black KTL coating
- Internal chamfer on tube facilitates assembly
- Chamfered screw holes for fastening wooden beams:
- 4× ø 8.5 mm for wood screws
- 2× ø 12.5 mm for wood screws or carriage bolts
- Support can slide along the shaft
- Support can rotate freely around shaft axis
- Outer dimension mounting plate: l=310 mm (12,2 in); w=55 mm (2,17 in)
- Sheet thickness: 5 mm (0,2 in)
- øi = 41.0 mm (1,61 in) ; øo = 57.0 mm (2,24 in)
- Height over axle GTS: 34 mm (1,34 in)
- Weight: 1605 g
- Article-No.: TTS2002
- HS code (customs): 73089059
- Slide the Static Support and the necessary Distance Rings onto the shaft of the GTS.
- Position the support beam on the bearing and screw it tight. The tree should have enough distance to grow (approx. 10 cm = 4 in).
- We recommend 6-8 mm stainless steel screws (small holes) and 10-12 mm carriage bolts (large holes) to fix the supports.

Frequently Asked Questions
At what distance do I position my support beam?
A normal tree grows around the Tree Screws by 2-8 mm (0,1 – 0,3 in) per year under normal conditions. The load-bearing capacity of our GTS Screws has been tested at a distance of 10 cm (support centre and support beam centre).
For Static Support, we recommend a distance of 10 to 15 cm (4 – 6 in) between the tree and the centre of the support under normal load. This allows the tree to grow undisturbed around the wound and form stable reaction wood before it eventually grows to the support beam.
The higher the load and the softer the wood, the closer the beam must be to the tree! With an oak and normal load, the beam can be e.g. 15 cm away. With the same load in a spruce, however, it would be better to choose a distance of 7 cm.
How thick must the support beams be?
To calculate the beam height use the following rule of thumb:
Here an example:
With such a cross-section, the beam may cantilever 1,0 m on each side. It is not the total length of the beam that is important, but the distance between the supports (here 400 cm).:
The calculated height h here is therefore 20 cm.
This value can be increased by 2 – 4 cm if very large loads are to be expected. The value can be reduced by 2 cm if only one platform is built without a treehouse and without large crowds. The beam width b should always be > 6 cm to have enough space for the bolting.
How do I transfer the height of my Tree Screws to other trees?
The same height can easily be determined with a hose level.
Be sure to note the difference in height between Static and Dynamic Support (see Assembly Instructions)!
You can find the common longitudinal axis with a compass (e.g. smartphone app): Transfer the compass needle (cardinal direction) from your already mounted GTS Screws to the drill, so that the alignment of your screw pair is almost perfect!
Alternatively, you can also stretch a string between the trees to simulate the beam. You can then apply a right angle to this string to show the alignment of the GTS Screws perpendicular to the beam.
