Primo Tools Horseshoe Spacers — Space and Shim Without the Compression

Soft spacers have a habit of lying to you. They feel right when you place them, then compress under the weight of a heavy tile and let the joint close up or a corner drop — and you don't notice until the row's already set. Rigid horseshoe spacers don't give: they hold their 3/16" dimension under load, so the joint you set is the joint you get.

The open horseshoe shape is the other half of why pros keep a jar in the bucket. Because it's open on one side, you can slide it in or pull it out at any point — no committing to spacer placement before the tile goes down, and no digging one out of a squeezed joint later. Stack two or three to shim height and level a first course or work across a substrate dip. They're reusable job after job, and they come in a 110-count jar or a 1,000-piece bulk box for bigger work.

Why Tile Pros Choose It

• Won't compress: Rigid build holds the joint under tile weight
• Open shape: Slide in or out anytime — spacer and shim in one
• Stackable: Dial in height for first-course leveling and substrate dips
• Consistent joints: Keeps courses straight and even
• Reusable: Built to survive many jobs
• 3/16" done right: The joint stays where you put it, not where the tile pushes it

Pro tip: Use them flat as shims under the tile to level a first course, and vertically in the joint to hold spacing — and pull them before the thinset fully sets so they stay clean and reusable.
