FireRock 03T175CRT3OY 3 Piece Pattern Mixed Size 1.75" Paver Set Oyster. Our 3 Piece Pattern is a large format random pattern. The use of larger pavers creates fewer lines for a more modern look. FireRock Pavers are offered in a variety of sizes and thicknesses, allowing you to custom select which options are best for your project. For both our 1" and 1.75" pavers, we deliver our A-frame packaging system directly to your job site, making for a smoother process from start to finish and less damage to our product. Our ability to mix colors and paver sizes (including all 7 sizes of our random pattern) on a single pallet makes for quicker installation, meaning less labor costs and job site headaches. Our pavers can be ordered as part of a pattern or as single sizes.
