Architectural Elegance Meets Hands-Free Convenience: The Concealed Self-Closing Pivot Hinge with 90° Hold-Open

Transform high-traffic interior spaces with effortless motion for doors up to 150kg—complete with an integrated hold-open feature and zero risk to underfloor heating.

Redefining How Heavy Pivot Doors Function

Large, architectural pivot doors make an undeniable statement in modern homes and commercial spaces. But keeping a heavy door open during daily life—whether hosting guests, encouraging open-plan airflow, or moving furniture—usually requires clunky, external floor stops that ruin your floor lines.

Enter the Arlu® (Argenta) Pivotica Pro 150 FM F90.

Engineered in Europe, this concealed self-closing pivot system gives architects, interior designers, and builders complete creative freedom. Built to handle heavy doors weighing up to 150 kg, the hinge remains virtually invisible when closed, delivering clean architectural lines with built-in operational flexibility.

What Does the “FM F90” Configuration Mean?

• FM (Floor Mounted): Surface-mounted footplate with minimal drilling depth, making it 100% safe for floors with embedded underfloor heating.
• F90 (Hold Open at 90°): Opens up to 150° in both directions with a built-in hold-position at +90° and -90°. When pushed below 90°, the integrated hydraulic mechanism automatically pulls the door back to a perfectly flush 0° closed position.

Selection Guide: FM vs. BI & F0 vs. F90

Ensure you choose the correct model variant for your project requirements:

1. F90 (Hold Open) vs. F0 (Free Swing):

   • F0: Free-swing function that always returns to 0° closed without a hold-open detent. Best for ensuite doors or privacy panels.

2. FM (Floor Mounted) vs. BI (Built-In):

   • FM (This Product): Installs directly on top of finished flooring with a 13mm bottom gap. Ideal for heated slabs or timber retrofits.

   • BI: Recessed baseplate built into subfloors for a minimal 5–11mm bottom gap.
