The 250 Pack Spacer Base is a key component of a professional tile leveling system, designed to ensure precise tile spacing and alignment throughout the installation process. As part of a friction-free leveling system, these spacer bases help maintain a flat, lippage-free surface while preventing tiles from shifting before the adhesive sets. Compatible with leveling cones and nuts, they require no special tools, making them an efficient choice for both DIY users and contractors. With 250 bases per pack, this set is ideal for large-scale tile installations using porcelain, ceramic, or natural stone tiles.
