Step 2:
•
Secure the 3m top support to two 3m uprights, there should be holes predrilled on the top
support for the M12 x 280mm bolts to go through. You can also use the extra 3m x
3” x 1.5”
and decking screws to brace the posts and keep them straight.
•
If holes aren’t predrilled
, you should drill a 32mm hole approx. 20mm deep on the top
support at each end. You should then drill a 12mm hole in the centre of the 32mm hole
through the whole post. Line up where the bolt will go through each 3m upright and drill a
12mm hole through each post.
