RTC Ultimate Leave-In Spacers – Rigid, Square Corner Spacers for Large Format Tile

RTC Ultimate Leave-In Spacers give distributors and retailers a premium upgrade over traditional cross spacers. Designed as square corner, rigid spacers that stay in the installation, they are ideal for large-format and rectified tile programs where joint accuracy and layout speed matter.

Their non-compressible plastic construction and longer arms make them easy for installers to handle, while the hollow “leave-in” body eliminates spacer removal and the callbacks that come from joints opening up after spacers are pulled.

Key Selling Points

• Rigid, Non-Compressible Body: Plastic construction will not crush under load, helping maintain true, uniform joint spacing on large-format tile.
• Leave-In Design: Hollow core allows grout to fill the spacer body and bond to the thinset, so spacers can be left in place – no removal labor and no tiles shifting after pull-out.
• Square Corner Geometry: Square design sits tight in the corner, ideal for grid layouts and rectified tile work.
• Longer Arms for Better Support: Extended legs support tile edges more effectively and make the spacers easier to grab and position.
• Stackable in Larger Sizes: 3/16" and 1/4" sizes can be stacked and snapped together to accommodate thicker tile or custom joint heights.
• Faster Install Workflow: No spacer removal step, fewer broken spacers, and more stable joints for large-format and wall work.
• Premium Positioning: Easy “good/better” step up from standard disposable spacers in your tile tools aisle.
