- Covers semi-fixed leaf widths from minimum 540 mm up to maximum of approximately 700 mm; mechanical opening angle limiter adjustable between approx. 80° and max. 120°; typical dimensions: ~277 mm length × 32 mm width × 42 mm height (for EN 2–4)
- Cushioned limit stay reduces impact at full open position; adjustable closing speed remains effective across temperature fluctuations; reversibility supports both left- and right-opening installations
How it works
This selector arm installs within the frame or door leaf, linking active and inactive leaves via a slide channel system. When the doors are opened together, it ensures that the inactive leaf closes first before the active one fully closes, securing correct latching—essential for smoke/fire rated assemblies.
