Schluter 1/8 inch Troba-ZFK Joint Spacer

TROBA-ZFK joint spacers ensure a uniform joint appearance for self-supporting porcelain tiles, natural stone, or concrete pavers installed directly on sand, gravel, or crushed stone beds. The joint width is 1/8" (3 mm), and the joint spacer height is 9/16" (15 mm). When thicker pavers are being installed, a joint spacer height of 1-3/16" (30 mm) can be achieved by snapping two joint spacers together.

The Schluter-TROBA-LEVEL paver support system enables the installation of self-supporting paver tiles for exterior applications. System components can be combined in various configurations to compensate for sloped substrates up to 5%, precisely level corners of adjacent paver tiles, and allow flush installation of pavers with different thicknesses. The elevated assembly provides easy access to the substrate, as well as drainage and ventilation. Due to the open joints between the tiles and pavers, surface water can freely drain on to the substrate and, if fitted, into the drainage system beneath.
