Schluter-TROBA-LEVEL™-PLV 60 adjustable paver supports are designed to support tile pavers of different formats and thicknesses. The supports can be variably adjusted from 2-3/8" to 5-1/8" (60 - 130 mm) using the height adjustment ring and two opposing threads. To achieve greater heights, TROBA-LEVEL-PLA 70 height extensions can be added between the height adjustment ring and the base plate.
