SNAPTiTE ASSEMBLY GUIDE
The Snaptite Assembly System locks end channels to all roof and wall sheets without the need for
tools and fasteners.
To assemble each panel, the perimeter channels are secured to the top and bottom of each panel.
Gently tap the channel over the SNAPTiTE lugs on the sheet, working along the sheet.
Each perimeter channel must finish flush with the edges of the sheets. Simply tap the channel along
the sheets until each end is neatly flush. If you need to remove channels from the panels, slide it off
from the side.
Channel locks the shed panel into
position without the need for screws!
FASTENING SYMBOLS
Secure channel to sheeting by SNAPTiTE
fastening method.
Join components together with one
screw at this location only, as some
channels have extra holes that are not
required for this model of shed.
Do not join components together at
this location yet, as the screws may
obstruct further assembly of the other
components.
Join components together by pre-drill-
ing the holes first. Use one component as
template to mark where the holes are and
drill with a 3mm drill bit.

Guide on Joining Spliced Channels
The text marked on all parts must be shown on the same side as each other
Step 1.
Position the channels and the
CSJ joiner so the centre of
the CSJ is in line with the end
of each channel to be joiner
together.
Step 2.
Join the first channel to the CSJ
by inserting the centre of the
CSJ, on an angle, to the end of
the channel where the JOIN>>
text is marked.
Push down one side of the CSJ
until you hear a ‘click’.
Step 3.
Join the second channel to the
CSJ by positioning the <<JOIN
of the channel at the centre of
the CSJ, on an angle. Push the
CSJ into the channel until you
hear a ‘click’.
Finished Channel.
The joined channels should
now look like the picture with
the CSJ positioned equally
inside of the joined channels.
Drill out holes with 3mm drill
bit in CSJ to match the holes
in channel and secure with the
screws supplied.
These may have to be
temporarily removed during
assembly.

PRE-ASSEMBLY OF SPLICED CHANNELS
NOTE: Some channels may have holes in them - You will
need to redrill holes where CSJ joining channel covers
them.
Join together 14x channel sections using 7x channel joiners (Part CSJ)
NOTE: Channels 55G, 55F, & 55H are best secured together using pop rivets through the 15mm high
(front) edge. This minimizes interference with the sliding doors
