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
• Complete kit includes: four rails, four bridges, one corner plate bracket, two metal base plates, six 5 mm bolts, eighteen 4 mm screws, six washers, and four thumbscrews — everything needed to assemble and secure precise 90-degree seams
• 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
• Adjustable leveling and fine-tuned alignment controls via thumbscrews for precise seam fit — even on inside corners (rails can be inverted for that purpose)
