Precision Flat Seam Setter & Leveling Jig for Granite, Quartz, Marble & Porcelain Slabs
The GRABO Seam Setter V2 gives stone fabricators and countertop installers absolute micro-adjustment control when pulling two flat slabs into a flush, seamless joint. Engineered with a rugged combination of stainless steel and heavy-gauge aluminum, this professional jig replaces unreliable manual suction cups with the unwavering hold of GRABO electric vacuum power—eliminating the slow pressure loss that causes joint separation halfway through an epoxy cure.
Equipped with smooth-turning mechanical adjustment dials, the Seam Setter V2 allows you to dial in height leveling, planar alignment, and seam closure with fractional millimeter precision. Whether setting delicate gauged porcelain panels or dense, textured granite tops, using a pair of Seam Setter V2 jigs ensures your countertop joints cure perfectly flat, tight, and ridge-free every time.
*Note: GRABO vacuum lifter tools are sold separately.
- Micro-Adjustable Seam Closure: Precision threaded adjustment knob glides slabs smoothly together or apart to establish tight, hairline epoxy seam gaps.
- Independent Dual-Point Leveling: Two vertical adjustment dials level out high-low lippage between adjoining slabs to ensure a completely flat finished surface.
- Eliminates Vacuum Bleed-Off: Leverages constant GRABO vacuum power to prevent premature release and joint slippage during critical adhesive curing times.
- Rugged Stainless Steel & Aluminum Build: Heavy-duty, corrosion-resistant chassis built to withstand daily shop fabrication and messy job-site adhesive setups.
- Universal GRABO Compatibility: Mounts directly to all authentic GRABO vacuum lifters, including GRABO Pro Brushless, GRABO V2, and GRABO High Flow models.
Versatile Applications
- Kitchen & Island Countertop Seams: Pull together quartz, quartzite, and granite seams on long runs and L-shaped kitchen counters.
- Large-Format Porcelain & Sintered Slabs: Level thin, gauged porcelain panels and sintered stone joints without cracking delicate edges.
- Commercial Stone Flooring & Walls: Micro-align adjoining vertical wall panels and flush stone architectural cladding.

FAQs
-
Is a GRABO vacuum lifter included with this jig?
No. This product is an accessory seam-setting jig. GRABO vacuum lifters must be purchased separately to supply vacuum holding force.
-
How many seam setters do I need for a typical countertop installation?
Professional stone fabricators typically use two Seam Setter V2 units across a standard 25-inch countertop depth to maintain uniform joint tension and balance across the entire seam.
-
How is this jig superior to manual pump-style seam setters?
Manual pump cups often suffer gradual vacuum bleed-off while adhesives cure, allowing slabs to shift out of alignment. GRABO tools maintain active, motorized vacuum seal integrity throughout the entire epoxy set time.
-
Can this jig handle 90-degree corner joints?
No. The GSS-V2 is engineered specifically for 180° flat, linear slab seams. For corner waterfall edges and 90-degree apron joints, use the dedicated GRABO 90 Degree Seam Setter V2.
