GRABO 90 DEGREE SEAM SETTER
TThe GRABO 90 Degree Seam Setter is the professional‑grade solution for creating perfectly aligned 90‑degree joints on stone, tile, or slab installations — ideal for kitchen islands, bar counters, shower corners, and inside corners where precise right-angle seams matter.
Features
- Engineered for 90-degree seam alignment — perfect for right-angle joins on porous or non-porous surfaces, including granite, marble, stone, tile, metal, and more

- Uses secure bolt-in system: six 5 mm bolts for base plate anchoring and eight 4 mm bolts to lock the angle joint — giving stable, rigid seams
