PVC-U Perimeter trunking systems
Technical information
Method of continuation through a
partitionwall
Continue the main lateral run of base
through the partition wall.Fit short
lengths of cover where the trunking
passes through the partition. The
partition wall trunking is then butted
up to the main run and the joint
covered by an internal bend fitting.
Offset dimensions
The minimum set that can be
accommodated in the same plane
(from internal to external bend), is
shown below.
Cable capacities
• All calculations allow for a 45% space factor.
As there can be differences between cable sizes,
Marshall-Tufflex recommend that cable dimensions are
confirmedwith themanufacturing company.
