Flush-Screed Trunking System

3 Compartment

Marco's flush screed trunking system has three large compartments designed to provide adequate cable segregation.

330mm Profile

Trunking has a wide 330mm profile, giving ample space to house a large number of cables.

Full range of fittings

The flush screed trunking has a wide range of compatible accessories and fittings. Outlet boxes for  the trunking also benefit from being compatible with the cavity floor box accessory plates.


The latest addition to Marco's underfloor range, our flush screed trunking system combined lengths of galvanised steel trunking with three compartment outlet boxes to provide a sturdy and robust system designed as a long term carrying solution for data and power cabling.
Flush floor trunking is a flexible solution for distributing services around large open-plan spaces such as offices or conference halls.
Service outlets and inspection modules can be installed in the trunking at various stages by removing lid and dividers from within the trunking system itself.
The service outlet boxes used for the flush screed system also benefit from using the same accessory plates as those used in Maeco's floor boxes.
