Definer +

Like the Definer range, Definer+ satisfies the requirements of the DDA but in addition it also satisfies new build Building Regulations. Definer+ is infinitely versatile and extendable. By simply adding and interlocking a mat with the DDA8 or DDA10 the profile can be extended to ensure full steps and landings are covered and completely protected against possible slips.
