TREEHOUSE SCREW – GTS SAFETY

The Plus in Safety

The GTS Safety is used to attach steel cables to the tree, to reinforce our large GTS and as a fixing screw for individual struts. Of course, you can also use the Screw to hang ropes, sun sails, fairy lights, flying roofs or nesting boxes.

Strengthen + Secure + Stabilise

The stainless steel GTS Safety is our smallest Tree Screw and does not have a long shaft and thus no lever arm – it can therefore take large loads despite its small dimensions. As a rope suspension it can be loaded vertically with approx. 400 kg (880 lbs) in softwoods and with approx. 800 kg (1760 lbs) in hardwoods. If the GTS Safety is pressed into the tree under pressure (Strut GTS + or Strut Support Safety), the load capacity is significantly higher! Installation is simple, the required trunk diameter ø > 25 cm (10 in) allows a variety of applications, even on thick branches, twigs and thin neighbouring trees.

Attach Cables and Ropes

Securing from above
The GTS Safety is also ideal for attaching cables and ropes directly to the tree. This way you can secure wobbly spots on your platform or attach sun sails and other things to the tree. With the Cable Suspension Set, you can reinforce individual GTSs from above.

Maximise load capacity

Reinforce the GTS
With the Strut GTS +, the load-bearing capacity of the large GTS Screws can be maximised or an overloaded screw can be subsequently secured from below. The load-bearing capacity can be almost doubled.

Attach struts

Stabilise from below
With the Strut Support Safety, you can quickly and easily attach individual wooden struts to the tree to provide additional support for your platform from below. Either directly during construction or afterwards, when you realise that your treehouse is a bit too wobbly.

The GTS Safety is used to reinforce our large GTS, to secure and support your treehouse construction and as a sling for thin ropes on the tree. It must never be used alone as a load-bearing screw for large loads. Get an overview with our product guide!

Frequently Asked Questions

Can I attach multiple ropes to a GTS Safety?

This is possible. The shaft of the GTS Safety protrudes approx. 2 – 3 cm from the tree, so that 4 wires can easily be laid next to each other.

Another possibility is to replace the stainless steel nut of the safety with an M20 ring nut or similar.

Of course, you can also use our large black GTS Screws for rope attachment to increase the load capacity, but make sure that the rope is tight against the tree to avoid large lever arms and jerky movements. You can secure the position of the rope with Distance Rings.

Can the GTS Safety be loaded in tension?

The tear-out strength of the safety is between 300 and 600 kg, depending on the type of wood. However, this load capacity should never be fully utilised!

Therefore, we recommend using the GTS Safety mainly for “hanging” rope angles < 30°. The Screw should be screwed in perpendicular to the course of the rope.

For flatter angles and predominant tensile loads (pull-out), it is safer to fasten the rope around the tree or branch with a tree harness / tree sling.

How thick should the cable / rope be?

The steel or Dyneema rope should be 6 to 8 mm thick, depending on the load. The turnbuckle can be chosen slightly larger in order to have more tensioning travel and leeway.

Be sure to check the exact load capacity of the rope with the manufacturer and get advice from a professional on how to properly compress the rope (thimbles, press sleeves, splicing).

Can I also use normal wood screws from the DIY store to attach ropes to the tree?

No!

  1. The screws available in DIY stores are not designed for extreme loads.
  2. A large diameter > 25 mm is required for fastening the ropes to the tree so that the screws do not bend.
  3. The screw thread must be deep so that it interlocks well in the tree and has a high pull-out resistance.
  4. Threaded rods can easily slip out (shallow fine thread).
  5. When building treehouses, you should always use professional Treehouse Screws!

We will be happy to help you! Please check our FAQ section first – there, we have already answered the most common questions for you.

In order to be able to advise you optimally, we need:

  • Sketches (drawn by hand is OK)
  • Position and height of the platform
  • Position and size of the treehouse
  • Photos of the trees
  • Tree diameter ø at the height of the platform
  • Tree species
  • Distance between trees (if more than one)
  • Use of the treehouse (many people, public, …)
  • Particularly stormy or snowy region?

 

“Since I often hang in trees or work with loud machines, it’s best to contact me via email. The more concrete your idea and the more detailed the description, the better I can help you – thank you!”
