Upgraded Tiling Clips: Inner 21mm high × 22mm wide, accommodates tiles 3-15mm thick. Pack of 100 units, set of 6 packs. Solid Reinforced Construction: The tiling spacers leveler features a solid, thickened top design for even load distribution and stability. Resistant to deformation and tear-through failure, it meets the demands of quality-conscious users. Break point Design: The root of the 3mm tile leveling clips adopt a breakpoint design to achieve uniform disconnection from the root, which can greatly reduce the workload used in cleaning up the residues inside the tiles. Does not Affect the Grout Line- The tiling clips are one-time use, the part of the clip broken after the tile is fixed is only 1-2mm, which does not affect the grout line. Notice: This product does not include wedges (illustrated for reference only). We recommend pairing with our 21mm wide x 16mm high reinforcement wedges at a ratio of four sets per tile., Manufacturer: Satisby
