Projoint DIL NZA is a natural aluminum movement joint made of two interlocking and sliding profiles. Suitable for ceramic floors, this movement joint is the ideal solution for surfaces subject to intense traffic, contraction and expansion movements of up to 3/32" (2 mm). NZA is notable for the high resistance it offers to loads as well as foot and vehicle traffic (fork-lift trucks, pallet jacks and cars). The perforated flanges guarantee perfect grip.
