The 324 design is popular because it's an alternate take on the popular torus profile. An added scoop detail at the top differentiates it from traditional torus designs. It's manufactured using premium moisture resistant MDF meaning imperfections such and knots, cracks and splintering are non-existent. The picture represents a skirting that is 150mm tall and 18mm thick. Note that the moulded section is approximately 42mm (from where the design starts to where it finishes) and does not change regardless of the height you choose. This product is 95mm in height, 18mm in thickness and 4200mm in length (will be much shorter than pictured above). It has a primed (white) finish. It does not have a rebate (space for cables to hide behind skirting).
