Big dreams or soft trees
When does the GTS Tree Screw need to be reinforced? When the screw reaches its load limit. This can either be because you are building a very large and heavy treehouse. It can also be that you want to strengthen the GTS because your tree is very soft (poplar, willow, spruce, redwood, ...). Or you may decide to enlarge your treehouse after a few years. However, similar to the Strut GTS + from below, you can almost double the load-bearing capacity of your GTS Bolts with the Cable Suspension! Of course, you can also combine both methods if necessary.
More Load Capacity
With the Cable Suspension, the load-bearing capacity of our large Tree Screws (Allstar, Top, Friend) can be almost doubled. Which system you choose, the cable suspension from above or the Strut GTS + from below, is irrelevant from a static point of view.
An advantage of the Cable Suspension compared to the reinforcement with Strut GTS + from below is the easy assembly and adjustment from the platform. The cable is anchored about 130 cm to the side above the GTS. Of course, it can also be shortened or lengthened, so you have plenty of leeway when choosing the attachment point.

2 Grooves for a Hallelujah
The Cable Extension is screwed onto the GTS instead of the M30 nut. The robust ø 8 mm cable can thus be attached further out so that the wooden beam can move freely without the cable and beam rubbing against each other. A second groove enables an additional rope stop and facilitates replacement.
What is delivered?
1 × Cable Suspension Set:
- GTS Safety (incl. nut M30)
- Steel cable ø 8 mm + turnbuckle M14 (lges = 130 cm = 50 in)
- Cable Extension (extension instead of nut M30)
- Steel cable and turnbuckle are pre-assembled ready for use!
- The rope extension sleeve is mounted instead of the M30 nut.
- Due to the far outward offset of the rope suspension, the rope runs past the beam unhindered – the wooden beam retains its full freedom of movement!
- The groove holds the rope in position.
- The second groove makes it easy to replace or extend the ropes. In this way, two ropes can also be mounted at the same time!
- The set can be retrofitted at any time!
Compatible with / for amplifying:
- Turnbuckle M14; DIN1480 (Ö/Ö)
- Steel rope ø 8 mm (EN12385-4 ; 6×19+FC)
- Ltotal = 130 cm (from end to end)
- Internal thread M30 (as for nut M30)
- Total weight of set: 4330 g
- Article-No.: TTS2006
- HS code (customs): 73089098
- Unscrew the M30 nut from the GTS and attach the cable extension.
- Open the turnbuckle almost completely (rope as long as possible).
- Find the desired point for the cable holder where the GTS Safety is to be screwed in. This is best done slightly to the side, as this activates more wood fibres (possibly on the side where GTS needs more support).
- Pre-drill a 145 mm deep hole with a 24 mm Auger-Bit – perpendicular to the course of the rope!
- Screw in the GTS Safety with a 1′ Ratchet.
- Tighten the turnbuckle firmly – done!

Frequently Asked Questions
When do I use Cable Suspension and when Strut GTS +?
Both systems are based on the GTS Safety as an anchor bolt and reinforce the GTS to the same extent. The rope suspension can be easily mounted from the platform and retightened from above. No additional steel parts are visible underneath the treehouse, but the rope guide above the platform can be disturbing, e.g. if there is a walkway or a wall there.
In some cases the tree dictates the type of securing anyway, e.g. no rope can be attached at the top because a large branch is in the way.
Triangular construction – Which GTS do I reinforce?
In a vertically loaded triangular construction, from a static point of view it is usually irrelevant whether the upper or the lower GTS is strengthened, because ideally it is an inherently stiff construction.
However, if the upper cross beam is heavily loaded and bends, a large part of the load is transferred to the lower GTS via the struts. In the case of 3D triangles, the lower GTS also tends to be loaded more by the struts, but this is also pressed into the tree and is therefore already more load-bearing.
The upper GTS, on the other hand, is sometimes loaded with leverage in tension – here a Cable Suspension would make more sense, as it wants to keep the screw in the tree, whereas the Strut GTS + tends to be in the tipping point.
As you can see, you can’t generalise. The best thing to do is to draw a sketch with your platform, the Tree Screws and the prevailing load. Draw force arrows indicating which GTS is loaded where and choose a suitable reinforcement accordingly.
Can I attach several reinforcements to one GTS?
Of course you can also reinforce your GTS (Allstar, Top or Friend) with several ropes and 2 Strut GTS +.
However, it often makes more sense to relieve the load on a Tree Screw by specifically supporting the adjacent parts of the platform with struts (Strut Support Safety or Strut Support GTS) or by using a free rope suspension (GTS Safety or Tree Loop around branch) from above.
