Channel is then placed over the row of fi xing-cones
(spacing approx. 50–100 cm). Suitable spaces are
made in the channel-fi lling to accommodate the
cones. Plastic bolts with washers are inserted
through the slots in the channel and screwed in
to the fi xing cones; this tightens the channel
HALFEN Fixing cone
