Sigma ST400 Work Table Clamps (2 per Box) — Lock Down Big Tile, Cut with Confidence Large-format tile and slabs that shift or vibrate while you work are dangerous and inaccurate — the cut wanders, the edge chips, and the piece can get away from you. These Sigma quick-release clamps firmly secure tile and slabs to your Sigma workbench, killing movement and vibration so you can score, drill, grind, and bevel with control. You get two clamps per box, and the quick-release design lets you reposition fast between cuts instead of fighting a slow lock. Built for Sigma tile workbench systems like the ST400, they improve both accuracy and safety on big-tile work. Pair them with Work Table spacers for penetration cuts. Why Tile Pros Choose It Locks tile down: Secures large-format tile and slabs against movement Kills vibration: Steadier work means cleaner, more accurate cuts Quick-release: Reposition fast between cuts Versatile: For scoring, drilling, grinding, and beveling Two per box: Clamp from both sides for a solid hold Safer work: A clamped slab can't get away from you Pro tip: Clamp on solid, supported areas of the tile — not an unsupported overhang — and use both clamps so the piece can't pivot. A few seconds clamping saves a chipped slab and a close call.
