You can either fix your strut with the “Strut Support Safety” (height adjustable / editors’ recommendation). Or you can screw your strut directly to the tree, in which case use permanently resistant wood for outdoor use (oak, robinia, heavy larch, …) and secure the strut with 4 long ø 8 wood screws.
Please follow our installation instructions exactly – this is the only way to ensure a permanently secure attachment!
Screwing in: Handle of 1″ ratchet; sturdy steel tube < 30mm; large pipe wrench.
Fixing to the wooden beam:
either laterally, or centrally (recommended). The slot must be 6 – 7 mm wide (common width of chainsaw chain). The wooden beam must be secured with 4 x carriage bolts ø 12 mm. The wooden beam should reach to the end of the sheet, you can drill out the hole with the 36 mm drill and work it sideways with a chisel for the welding seam.
Do not use the GTS Side without an additional brace construction (triangle / bracket).
Avoid large leverage forces and lateral rotation. Secure your construction against tilting with opposite screws / brackets!
