Maximise the load capacity of your German Treehouse Screws!

‘Cable Suspension’ becomes necessary when the GTS reach their load limits (see load capacity of softwood and hardwood).

  • For large projects
  • For high load peaks: Storms, snow, crowds, earthquakes

The set can also be installed subsequently:

  • When expanding and extending the treehouse
  • In case of unexpectedly soft wood (old GTS screw is threatening to sag)

If the rope course bothers you, you can also reinforce our GTS screws from below: see ‘Strut GTS +’

Order details

The set consists of:

  • GTS “Safety” incl. nut M30
  • Steel cable 8 mm + turnbuckle M14 (ltotal = 130 cm)
  • Cable Extension (extension instead of nut M30)

Steel cable and turnbuckle are pre-assembled ready for use!


Product details

  • The “Cable Extension” sleeve is attached instead of the M30 nut.
  • Due to the Cable Suspension being shifted far outwards, the cable runs past the support beam unhindered – the wooden beam retains its full freedom of movement!
  • The recess / groove holds the rope in place.
  • The second recess allows easy replacement or extension of the ropes. In this way, two ropes can also be attached at the same time!
  • The set can be retrofitted at any time!


Technical data

  • DIN quality steel
  • Black KTL Coating
  • Turnbuckle M14; DIN1480 (Loop/Loop)

  • Internal thread M30 (as Nut M30)

Field of application

The set has the following function:

  • The load-bearing capacity of the large GTS is greatly increased.
  • The beam is additionally secured from slipping.

Can be used in combination with:

  • GTS Allstar
  • GTS Friend

Note triangular construction:

If the rope course at the top interferes, you can also secure the lower bolt of the triangle construction.

Do you want the ultimate load capacity? Then combine “Cable Suspension” and “Strut GTS +”.


Please follow our installation instructions exactly – this is the only way to ensure a permanently secure attachment!

For the installation you need:

  • Pre-drilling Safety: Auger Bit 24 mm
  • Screw in Safety: 1″ Ratchet (if necessary another ratchet or open-end spanner with extension)
  • And the pre-mounted large GTS screw to which the rope will later be attached.


  1. After the large GTS tree bolt has been mounted, remove the nut and screw on the sleeve of the “Cable Suspension” instead.
  2. The “GTS Safety” is mounted above it (slightly offset to the side).
  3. The steel cable that connects the “Safety” and the tree bolt underneath is tightened with the help of the turnbuckle.

Here you will find sexy installation videos and detailed step-by-step instructions. Notes:

  • The rope and the wooden construction must not rub against each other.
  • The rope and turnbuckle must not be bent over the edge.
