INSTALLATION NOTES
When verifying the stability of the structure, consider the following external factors:
1. The strength of the floor.
2. Exposure to sudden and severe wind.
3. Danger arising from contact with people and / or objects. (eg installations
in passageways, emergency exits).
• Install stand on level ground • Minimum two person assembly

ii. Attach next vertical columns one at a
time and fix with the joining bars.
Note: Do not extend columns over 4.2M
i. Fix a column to each base and attach the
first rail to make the structure stable.
Installing columns with a height over 2.4M
B-Tech recommends when extending the vertical columns over 2.4m to fix the first two columns (item B1)
to the bases (item A1) and connect with a horizontal rail (item D1) and then build up, rather than building
the product layed down on the floor (as shown in the assembly instructions).

i. Insert the joining bars (item B7) halfway into
the non-threaded end of the column (item B1).
The two joining bars with grub screws (item B8)
go in the front of the column and the 2 joining
bars with hex bolts (item 9) go in the back.
IMPORTANT: Joining bars should be
inserted into the non-threaded end of
the 180cm column.

i. On the intended front facing side of the mounting rail (item D1) insert 4 x joining
bars (item F1) half-way into each slot, on the back side insert 1 x joining bar into
the top slot and 1 x joining bar into the third slot (see fig. 1). Loosely fasten the
2 grub screws (item F2) on each joining bar fixing it to the mounting rail.
ii. Slide another mounting rail (item D1) onto the joining bars and tighten all the
grub screws, combining the rails securely.
