• Base of trunking to be butt joined
together.
• Secure trunking base every 500mm
by drilling oversize holes and

opposite fixing points.
•

smaller compartment to the top to
align with fabricated fittings.
Joints and bends
• Internal and external bends and
angled tees are fabricated.
• Butt join trunking base to fabricated
fitting.
• Covers of fittings extend over the
base to assist alignment with the
trunking.
• End caps with clips ensure security of
trunking.
Covers
Covers are designed to limit
unauthorised removal and to remain in
position during normal conditions
irrespective of impact and minor
undulations of the mounting surface.

fitting to gain access. Insert blade of
terminal screwdriver between captive
legs of cover and base and gently ease
