Fittings bought separately rarely fit properly. A coupling moulded to a different tolerance sits proud, an elbow from another maker leaves a step inside the bore, and the installer ends up filing plastic on site to make a neat job.

Our fittings come off the same moulds as the profile they clip onto, which is the only reliable way to guarantee the fit. A buyer ordering trunking and fittings together gets parts that were designed as a pair rather than matched by dimension after the fact.

Double sided tape belongs in the same order. On a finished wall, drilling is the objection that stops a job, and a trunking run fixed with tape goes up without dust, without a plug and without an argument with the building owner.
