ASSA ABLOY Shaft Extension SEK – M10 (for SW200 / SW300)

ASSA ABLOY Shaft Extension SEK – M10 (for SW200 / SW300)

The Shaft Extension SEK (M10) is a precision-engineered accessory for ASSA ABLOY SW200 and SW300 swing‑door operators. It is specifically designed to enable automation of arched or curved doors, or doors with increased pivot depth, by extending the spindle/shaft length without compromising system performance.

Key Features & Benefits

• M10 Threaded Extension
  The M10 specification provides a strong, standardised interface for extending the operator shaft, maintaining alignment and mechanical integrity.

• Supports Arched & Curved Doors
  Ideal for applications where the door leaf or frame geometry requires greater spindle reach—for example, curved glazing, radius‑mounted doors, or deep mount custom frames.

• Compatible with SW200 and SW300 Operators
  Designed to integrate seamlessly with ASSA ABLOY’s SW200 and SW300 swing‑door units, enabling extended mounting depths while preserving factory‑calibrated mechanisms.

• Reliable and Durable Construction
  Manufactured from robust materials to withstand the stresses of heavy use in commercial or public access environments.

• Facilitates Custom Installations
  Enables installers to adapt standard operator installations to non‑standard door geometry without redesigning the drive unit or replacing the system.
