Among the new design features are a double-folded safety edge on the return of the trunking, which is safer for handling and cables.
The external coupler is wider and stronger than the previous coupler to hide cuts made on site and ensure good earth continuity. The coupler is supplied prefitted to save time. Slotted ends on all lengths enable the trunking to be slid into place and secured with minimal effort.
Multi-head shake-proof screws aid installation flexibility. They have a serrated flange that bites into the steel to help earth continuity and are supplied assembled to all couplers and fittings, backed off to accept the next component so no more bags of screws go missing.
Finally, push-fit spring-loaded quarter-turn turnbuckles make for fast and secure fitting and easy maintenance.
