G1600 is a hydraulic door closer rated for doors up to 1200 mm wide. It belongs to our door-closer series, for everyday residential and commercial openings.
Our catalog writes this door weight as an upper limit on a range, so the lower figure is not a minimum door weight. The exact rating is pending factory confirmation.

Dimensions and installation
What you can adjust
- Two-stage closing speed. The main swing and the final latch are adjusted separately — the factory quotes 180°–15° for the sweep and 15°–0° for the latch. In practice that means you can slow the door down without leaving it too weak to push the latch home.
- Adjustable closing power. Closing force is set on the unit itself rather than fixed at the factory, so one model covers a range of door sizes and can be tuned after it is hung.
