Flush Floor Screed Trunking

A range of heavy duty floor trunking for use in screed with the lid flush with the finished floor level, giving the flexibility of re-wiring and moving outlet points without disturbing the screed.


Upper surface is a removable cover, either flat or recessed to take floor covering. For recessed lids a stainless steel option is available.


Trunking available in any width, any depth, any compartment


A range of sizes held in stock from 150x25mm to 330x65mm


Floor service outlet boxes can be fitted at any point along the trunking run, at any time after screeding when using trunking at least 55mm deep.


We can adapt both trunking and service boxes to suit your existing installed trunking


All ranges can be fitted with gasket

The lids should be in position when the screed is poured to prevent the distortion of the side walls.
