RTC Universal Protection Plates — One Plate for Every Leveling System If you run more than one leveling system, you don't want a drawer full of system-specific shields. RTC Universal Protection Plates work with both spin-cap and clip-and-wedge systems, sitting between the tile and your cap or wedge to guard polished finishes from scratches. Their anti-friction surface converts twisting or wedge pressure into clean vertical clamping — so the tile pulls flat without the shield dragging on the face. You get 100 plates per box. For a spin-cap-only setup, the Spin Doctor Anti-Friction Shield is the dedicated match; either way, run them with your caps on scratch-prone tile. Why Tile Pros Choose It Universal fit: Works with spin-cap and clip-and-wedge systems Protects finishes: Shields polished and delicate tile faces Cleaner clamping: Anti-friction surface converts pressure to vertical clamp 100 per box: Enough for a full scratch-prone install One SKU, any system: Simplifies what you stock on the truck Ends the shield shuffle: No more hunting for the right brand's plate Pro tip: Use a plate on every fastener when the tile is polished or dark — the anti-friction face is what keeps the twisting cap or driven wedge from marring the surface. Keep a box with each leveling kit so they're always within reach.
