Reliable, Rigid Spacing for Perfect Tile Alignment

RTC Ultimate Horseshoe Spacers are engineered for tile pros who demand predictable, consistent spacing on every project. Their rigid U-shaped design hugs the tile edge, stays put without compression, and gives you a rock-solid reference for even grout joints. Whether you’re stacking wall tile, setting heavy porcelain, or fine-tuning lippage on large-format installations, these spacers deliver the accuracy you need without slowing you down.

Unlike traditional hollow back spacers that twist or collapse, these solid horseshoes maintain their exact thickness under pressure—making them ideal for pros who want clean lines and tight tolerances. Plus, they’re reusable, easy to grab with gloves on, and stack effortlessly for micro-adjustments.
