BackUp from Below
The Strut GTS + is a robust turnbuckle that allows you to reinforce and secure your GTS from below – so you get the most out of your Tree Screws!

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 Cable Suspension from above, you can almost double the load capacity of your GTS Bolts with the Strut GTS +! Of course, you can also combine both methods if necessary.
More load capacity
With the Strut GTS +, the load-bearing capacity of our large Tree Screws (Allstar, Top, Friend) can be almost doubled. From a static point of view, it doesn’t matter which system you choose, the Cable Suspension from above or the Strut GTS + from below. The advantage of the Strut GTS + is that the space above your support beam remains free.
Anytime – Anywhere
The Strut GTS + can be mounted whenever you feel that your GTS needs more power. Depending on the GTS model and strut angle, the anchor point is about 50 cm vertically below the bolt to be reinforced. You are free to choose where you place the ring on the shaft, but we recommend mounting it on the very outside for a maximum triangle of force.
Turnbuckle ø 35 mm
Wedged in firmly
The Strut GTS + is anchored vertically under the GTS in the tree with the GTS Safety. In case of heavy one-sided loading, the construction can also be moved slightly to the side for better load bearing. Use a thick screwdriver to turn the turnbuckle and wedge the prop firmly in place!

Frequently Asked Questions
When do I use Strut GTS + and when Cable Suspension?
Both systems are based on the GTS Safety as an anchor bolt and reinforce the GTS to the same extent. Both can be retrofitted and are easy to adjust. The Strut GTS + gives you complete freedom above the support with the bearing beams, which is great if there is a wall there, for example.
In some cases, the tree dictates the reinforcement method anyway, so you can’t mount a Strut GTS + below it because there is a large branch.
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.
