Product details
The set includes:
- 1 x GTS Free (incl. nut M30)
- 4 x full thread wood screws ø 8 x 120 mm, gold galvanised
You need the full thread wood screws to reinforce your wooden beam in the area of the drill hole!
You don’t need an extra support if the load is low!
Both the hole for the coarse thread in the tree and the hole in the support beam are pre-drilled with a 36 mm Auger Bit.
With the GTS Free, the wooden beam is inherently close to the tree. If strong thickness growth (tree) is to be expected, we recommend using a larger GTS with Support and Distance Rings
Not recommended for swing beams, cantilevered, rotating or swinging elements!
Technical data
- Stainless steel A2
- Length ges = 285 mm
- Length thread = 100 mm
- Drilling depth in tree = 130 mm
- Length shank = 120 mm
- Diameter shank ø = 34,5 mm
- Nut M30: stainless steel SW 46
- Shaft end with SW 30 (here you can use open-end spanner or pipe spanner)
Field of Application
- Small trees
- Mini platforms < 10 m²
- Low, even load
- Small children’s playhouses
Perfectly suited as an alternative for “clamping and pincer technique”, for platforms in:
- Climbing forest
- High ropes course
- Adventure course
Threaded rods in the tree as fixings for platforms are only suitable to a limited extent – they are not built for bending and shear loads. Threaded rods should only be loaded in tension!
Not recommended for swing beams, cantilevered, rotating or swinging elements!

Installation Instructions
Please follow our installation instructions exactly – this is the only way to ensure a permanently secure attachment!
Note, drilling directly through the wooden beam is a weak point – reinforce your wooden beam:
- The wooden beam must have a minimum dimension of 120 x 60 mm (better 160 x 80 mm!).
- Make sure the supporting beams are of high quality and strength.
- The drill hole (centre) must be about 2/5 of the height of the beam at the bottom (e.g. at (120mm / 5) x 2 = 48 mm from the bottom).
- Reinforce the wood about 2 cm next to the drill hole with the 4 fully threaded screws supplied. Keep the fully threaded screws about 2 cm away from the edge; pre-drill the holes with ø6 mm to avoid splitting.
- If necessary, reinforce the wood additionally with a sheet metal plate or a stable DIY construction.
