The Omni Cubed Stealth Seamer 90D, Manual – 5" Cups is the professional solution for achieving precise 90-degree stone seams. Whether working with mitered aprons, butt-joints, compound corners, or inside corners, this tool ensures consistently even and aligned seams—without relying on straps or bar clamps.
Unlike other seamers, the 90° Stealth Seamer Manual can be inverted to handle inside corners, giving fabricators maximum versatility. Its non-marking synthetic rubber vacuum cups feature FTS™ triple-seal technology, providing a powerful, reliable hold even on textured and leathered stone surfaces.
For precision control, knurled rollers and fine-tune levelers allow installers to dial in exact angles, while the integrated counter-pressure leveler helps eliminate lower outswing on vertical pieces. Easy-to-read vacuum indicators make monitoring simple, and the re-pumpable cups maintain pressure without removal.
Built with UV-resistant, weather-resistant, and tear-resistant synthetic rubber cups, the 90D Manual combines long-term durability with non-marking performance—perfect for today’s lighter materials like white marble.
Sold individually; recommended for non-porous stone materials only. For heavy waterfall applications, see the Omni Cubed 90° Auto Seamer.
