Assembly
This tower structure must be assembled, and components oriented, in accordance
with this instruction manual. Deviation from this instruction manual is not permitted.
THIS TOWER MUST NOT BE USED AS AN ANCHOR POINT
FOR PERSONAL FALL PROTECTION EQUIPMENT.
•
No tools are required for assembly.

The assembly uses the 3T (Through the Trapdoor) method that provides
collective fall protection.
-
From the sitting position in the trapdoor opening fit all guardrails before
standing on the platform.
-
Fit braces in the locations described
and ensure the claws are locked.
•
The tower may be assembled by a single person, but it is recommended that
two or more are used to pass up components on the taller assemblies.
•
Components must be lifted within the footprint of the tower using a reliable
method such as a strong rope with a clove hitch knot.
•
Always start assembly with the smallest height frames at the base.
